Can't see an option for lowlatency. Can this feature be added?

I keep trying to switch off the dialogue boxes so that I just get the notification bubble, but the setting never saves from session to session, so I always get the popup box which I really don't appreciate. Every other setting, at least the ones I have altered (frequency of check, hiding older kernels and unstable+RC versions), appears to save fine.

Running Ukuu v 18.1 on Linux Mint 18.2 (just upgraded to 18.3).

On Ubuntu 17.10 the Ukuu Window disapears after i remove a installed kernel but the process is still alive.

In the syslog i found this message after (but i'm not sure if its realy related or another bug):

Jan 17 21:14:46 xxx ukuu-gtk[18500]: Drawing a gadget with negative dimensions. Did you forget to allocate a size? (node progress owner GtkProgressBar)
Jan 17 21:14:46 xxx ukuu-gtk[18500]: Allocating size to MainWindow 0x55b074d92420 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?
Jan 17 21:14:47 xxx ukuu-gtk[18500]: message repeated 11 times: [ Allocating size to MainWindow 0x55b074d92420 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?]

It would be a nice enhancement to have the application write the screen output to a file.

After installing a kernel, a window pops up that says something like "Booting previous kernels...". I am unable to read the rest because the window is essentially only wide enough to fit one character per line (I could surely read it all, but heck I'm not gonna read several sentences of vertical text).

I am running Ubuntu 17.10 with GNOME 3.26.

After installing a kernel, ukuu leaves the downloaded .deb files in $HOME/.cache/ukuu/... Even after uninstalling a kernel these files are left behind filling the disk unnoticed by the user.

Could you please implement a feature to delete these downloaded files. I would prefer a configuration option with these possibilities:
What to do with downloaded files?

• Delete downloaded files when uninstalling a kernel.
• Delete downloaded files after installing a kernel.
• Ask what to do with the downloaded files after installing (and after uninstalling) a kernel.
• Ask what to do with the downloaded files after uninstalling a kernel.

IMHO the overview should show, if files are downloaded, e.g. with an additional column (Downloaded, Partially downloaded). Another option would be to incorporate it into the Status column: Running, Running + Downloaded, Installed, Installed + Downloaded and Downloaded. An additional button Clear below Refresh, Install, Remove would remove the downloaded files.

I just wanted to drop a line and say thanks for this app. Since the Meltdown and Spectre issues I've been using it a lot more often than usual.

I was just wondering if anyone ever thought to modify this app slightly for aiding kernel bisects. The use case would be as follows:

When a Bi-sect is needed,, the Ubuntu Developer would set up a space on FTP (like they do already). This ftp would then be added to UKUU and used to fetch the latest bisect. Once the user installs a kernel for a bisect. In UKUU, the user would flag the kernel (OK/Not OK) and save. On the developer side, he'll see that the kernel was tested and if needed, generate a new one (which would then be visible for the user to test).

Anyway, it's just an idea. I did a bi-sect for an issue which took months only to fail and have to start over again. I think a GUI tool for end users would definitely help speed this process up an make it less error prone.

Sometime new linux kernel build failed in the mainline kernel from ubuntu. Which will cause error when install. Please add warning to those kernel build.

Dear teejee2008,

First, I love a lot of your applications, including Ukuu. Thank you so much for providing these for all of us.

I do not know if this request should be part of a couple other requests I see in this.

Can you add or modify Ukuu to show and use "low-latency" Kernels in addition to LTS and Real Time (RT) Kernels?

Out of curiosity, why wouldn't everyone want a low-latency or Real Time (RT) Kernel? Why is that not the default for Linux Kernels? Which is better Low-Latency or RT Kernel?

Best regards to you and yours,
Phil

Using Ubuntu, ukuu v17.2.3 and KDE, after installing a kernel a message is given which is poorly sized, making it unreadable:

Please add support for filtering/displaying Realtime Kernels.

In my opinion, outputting most recent kernels first from ukuu --list is non ideal, since the kernels 99% of use cases require will be hidden by older ones.

On first run, however, current install info and all but the oldest kernels are displaced by 'errors' that ukuu cannot find a cached version of each kernel's info. This info should be a warning and should be supressable.
Running ukuu --list from Ubuntu 17, there are enough kernels and errors that kernels 3.x.x and 4.x.x are not visible in the list, even by scrolling back the page.

The command line version can currently be used only if a display is available. Remove dependency on X and GTK.

Where are ukuu CLI version configuration? Would it be possible to set minimal kernel version for update (--check but also when installing with --install-latest)? It could reduce the amount of data to download and speed up updating and ukuu working in general. It could be also an additional parameter, e.g. --min-kernel-version v4.15 or similar while running the ukuu. Then it would be easier also to run using central software management tools, also scripting. Similarly there could be also e.g. --max-kernel-version v4.16.2 to limit also highest version. Then the --install-latest will e.g. install the latest one that fits into min and max limits.
Looks like configuration is located at ~/.config/ukuu.json - is there any documentation of it?

The Ubuntu mainline kernels come with GPG-signed hashes (CHECKSUMS, CHECKSUMS.gpg), but this utility ignores them. Since the downloads are over plain HTTP, there is nothing to stop a network attacker from modifying the kernel packages in transit.

Can we get the notification dialog to appear only once? Or not appear again until the previous one has been acted upon? This is my backup machine, which I haven't logged into for about 10 days. When I connected, I find the desktop overflowing with UKUU popups. It's kind of ridiculous.

I have ukuu set to check every two weeks for updates. Ukuu seems to contravene the setting by notifying me, before that time has elapsed, about point releases.

ukuu 17.12 on Mint 18.3 x64.

EDIT: I have two Mint computers. On one, update is set to 21 days. That PC seems not to have the problem. The other computer uses the 'weeks' value, that value being set to '2'. That computer has the problem.

FURTHER EDIT: on reflection, perhaps there is no mistake. The kernel concerned (Ubuntu 4.14.6) has been out for only a day, I believe; but perhaps the computer concerned last checked less than two weeks ago. So perhaps I am just being a nuisance; but perhaps also it would be worth checking your code . .

I am running kernel v4.10.6, and have kernel v4.10.8 installed. Despite this, Ukuu still notifies me that there is an update, v4.10.7, to be installed.
I believe this shouldn't happen as I already have a newer kernel verison installed. Is it a bug?

[I have edited what follows, in order to make it clearer.]

The link within the text

Source code and binaries are available from the GitHub project page

Takes one to the very same page on is on (and not even to any particular location on that page) - that page being https://github.com/teejee2008/ukuu.

EDIT: also, I can't work out how to build the application from the git clone. Neither the build-source file nor the build-installers file seems to do the job. The latter file produces this error message:

dpkg-deb: error: failed to read archive 'release/ukuu-v18.1-i386.deb': No such file or directory
Failed

Further EDIT: oh, I should fall the instructions in the file called 'INSTALL'? Something telling one that - a file called 'README', or something on this website - would be good.

I could not find a configuration file for ukuu anywhere on my computer after installing it nor did an inspection of the .deb file reveal anything. Ukuu would be much better if there were means to configure how it works and if there was a man page for it. I would propose allowing the user to set up which kernel repositories it can use to include non-Ubuntu and kernels other than "mainstream" when using the Ubuntu kernels. There probably should be separate configuration files for the command line and it's GTK app as well as a file that holds all of the kernel repositories ukuu accesses.

Could you somehow make a setting option that only shows the latest LTS kernel and update it with point releases.

I'm running the Ubuntu 18.04 beta. I used Ukuu to update to 4.16, and have Nvidia 390 installed on an optimus laptop. glxinfo reports that mesa is the renderer instead of the proprietary driver

When using the Wayland session instead of X.org, UKUU stops working with the following message:

can you adapt your ukuu utility to deepin

A few days ago (before the new update) I was able to use ukuu to update my kernel to version 4.15-rc7. I have since had to reinstall Ubuntu so I tried to update my kernel again and the newest version ukuu shows when running --list is 4.14.13. I have checked on a second computer and get the same result. Is there a way to install the previous version of ukuu (before the update 2 days ago) so I can see if that still works?

Since the last update, Ukuu only shows this message and doesn't find any kernel to download.

Ubuntu 17.10
Kernel 4.14.13

When pressing the Changes button with a kernel release (the newest) selected, nothing happens.

ukuu-gtk --debug does not show any error message.

ukuu always shows no internet connection dialog box but can get all the new kernels.When installing the same no internet connection error occurs

Using the CLI the following error is received:

$ sudo ukuu --install 4.13.4
[sudo] password for : 
Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused

(ukuu:7669): Gtk-WARNING **: cannot open display: :0

ukuu worked once, but crashed now consistently over reboots. Probably due to a glibc update latey.

See attached screenshot as copy&paste does not work

More of a feature request than a bug.

As the title says, at the present time Ukuu doesn't provide a list of kernel types to chose from via settings, instead it is hard-coded to use -generic which is fine for most people. That said, it would be nice to be able to tell Ukuu I want the -lowlatency kernel instead of the -generic kernel.

Hi,

I notice that UKUU does not install linux-tools(-common) for the installed kernel.

I came across this after updating to 4.10.10 on my Elementary Loki machine. Under the new kernel tlp-stat complains:

x86_energy_perf_policy: program for your kernel not installed.

I guess this isn't critical but on a modern laptop I understand that this does effect power consumption. "cpupower" also complains that the packages are missing for the running kernel.

Thanks,
Steve

I've been having problems with using ukuu to upgrade to v4.10.13 and checked http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10.13/ only to find all the builds marked 'failed'. ukuu upgraded everything up to v4.10.12 fine and when I checked v4.10.12 the builds are marked 'succeeded'. Does ukuu check whether the build is marked succeeded or failed?

Thank you for the latest update, and more generally for this tremendously useful piece of software.

On version 17.12 of ukuu, as indeed on previous versions, my text editor - Sublime Text 3 - gives an error when (via ukuu's useful 'changes' buttun) it (Sublime) opens the changelog. See screenshot.

Sublime does not normally show this message on my system. I think the cause might be a bash script setting the character 'encoding' (for I did once make similar problems myself with a script).

With the recent kernel updated, the building of the ndiswrapper failed with the following error message:

Is this ukuu's, ndiswrapper's, dkms's or the kernel's fault? An Internet search turned up nothing (at least with the search engines I used)...

Ubuntu 16.10: Lots of error messages with ukuu and new kernels not able to be installed.

It would be helpful to have build instructions for Ubuntu (unless they are there and I missed them)

I probably have other GTK libraries installed, but:

I could successful run make with the following in Ubuntu 17.10:

sudo apt install valac libgee-0.8 libjson-glib-dev libvte-2.91-dev

At the UKUU download page the downloads are all offline: http://www.teejeetech.in/p/ukuu-kernel-upgrade-utility.html

seems like the dropbox wasn't such a good place to serve the sownloads ;)

Could you fix the download links please? I would like to install ukuu on Debian.

While installing a kernel via ukuu, ukuu produced a notification advising me of the existence of that very same kernel.

ukuu v18.1

Using ubuntu 16.04 based KDE Neon with Wayland and getting error:

No protocol specified
Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: Connection refused

(ukuu:6000): Gtk-WARNING **: cannot open display: :1 

Close window to exit

Since MIR is dead, feel free to prepare UKUU to support Wayland :) it's move in right way.

Thank you

The title basically says it. I'm not booting into a gui environment but to terminal usually.
Using ukuu there is basically impossible because it requires a running x-server. Please make "ukuu" a pure terminal program.
