0.1.11.0 crash about fluentterminal HOT 21 CLOSED

No, mine refused to run, but I did notice that the x64 2015 UWP runtime failed to install correctly, and installing it from the Dependencies folder didn't work (I had to install it form Powershell with Add-AppxPackage as it looked like the install window itself was causing the conflict, which was confusing).

from fluentterminal.

I run Add-AppDevPackage.ps1 by manual, and it works now.

from fluentterminal.

Found it! I think.

This is a bit misleading, and I don't know what exact functionality is causing it, but if you just choose Sideload Apps in the Windows 10 developer settings, this is the behaviour you get. If you enable Developer Mode, without reinstalling anything, you get the correct behaviour. Ideally we wouldn't have to enable full-on developer mode to sideload the app, but I don't know what functionality we're using that triggers the issues.

Edit: Process: Confirmed on a fresh install of Windows 10 1803 (defaults to "Sideload Apps"). Installed the cert to Local Machine\Trust Root, double-clicked on the .appxbundle, opened the app, the UWP portion crashed, and the tray processes stayed alive. Closed the tray process, enabled Developer Mode, relaunched the app, and it opened correctly.

Sort of the last update I think on this:

I tested this by building it and explicitly revoking the LoopbackExempt status from the development package, and indeed what happens is that the websocket in the JavaScript side times out, and issues a .onclose(), which sense CloseTab to the terminal bridge.

So this is indeed caused by the same headache that's present in #34 . I'll make a PR that updates the README on how to install to note that if you're sideloading the app, you'll need to run the above PowerShell snippet

from fluentterminal.

Can you please open then Windows Event Viewer, go to Windows Logs -> Application, start the app and tell me the error details?

From your screenshot I can tell that both App and SystemTray are working, and a powershell has been created. Does your Powershell work when you start it in its native window?

from fluentterminal.

I haven't got time to open an issue but this is the very behavior for me since 0.1.9.0. Tried all versions and none of them even opened (can get to the settings view and change everything, but the application closes without any output).

The app launches (and closes), there is a tray icon, but there are no events in Event Viewer.

from fluentterminal.

Did you try with CMD as the default shell? Same behaviour?

from fluentterminal.

Tried with CMD, Powershell, and even WSL Bash. Same behavior as above (closes, no events).

from fluentterminal.

Ok, then I'm out of ideas for know.
Maybe you can find some time and try to debug it on your machine?

from fluentterminal.

There's likely been some changes to the stuff stored in the roaming preferences/settings. If you aren't married to your FluentTerminal settings, try uninstalling the app, and installing the new one fresh? A less destructive, but also likely less decisive test, would be to just reset the app's data.

from fluentterminal.

Tried uninstalling and reinstalling several times, also tried removing any directory named FluentTerminal in %APPDATA%.

from fluentterminal.

@felixse I know this is out of scope of this issue, but can you provide dependencies and appx + cert as separate downloads, it's hard to download 80MB bundle repeatedly while on roaming? (I didn't want to open an issue to ask this.)

from fluentterminal.

Ok, so all I can offer you right now is to wait for the next release. I will add some logging to see whats going on.

I can provide a package without dependencies. This will only save 16mb, but better than nothing

from fluentterminal.

@felixse The problem got fixed after repeated installations (yes, repeated) of dependency packages and manually installing the cert file multiple times. 🎉🎈

A check for dependencies in the main launcher file?

And regarding package and dependencies, it looks like appxsym files are not required for installation (these files make up ~45MB of the total app). If these files are not required then the app would only be ~36MB.

from fluentterminal.

Nice to hear you got it working 😃
Nothing we actively do on our side, must be some weird appx installation bug.

appxsym seems to contain debug symbols, I think we can strip that as well for the 'light' download

from fluentterminal.

I was able to reproduce it on a brand new install of Windows 10 1803 x64 in a VM, so there's something super weird going on here.

from fluentterminal.

And you got it running after trying it multiple times?

Tried it myself in a fresh 1803 VM a few days ago, but in my case it installed correctly at first try 😕

from fluentterminal.

Can you check whether the loop back exemption is set (you can use this to look it up: https://archive.codeplex.com/?p=loopback) when you are in the ‘crashing state’?

from fluentterminal.

Got it:

I have confirmed that running

CheckNetIsolation LoopbackExempt -a -n="(
    (Get-AppxPackage | where { $_.Name -eq "53621FSApps.FluentTerminal" }).PackageFamilyName
)"

after installing the certificate and .appxbundle will fix the crash without requiring that you change the developer settings from "Sideload Apps". You'll need to run the command as administrator, but it will explicitly add the missing loopback permission for only the FluentTerminal app.

from fluentterminal.

Well, at least we found the issue and also a work around. I would consider this as resolved now, thanks to everyone who contributed here 😃

The fun continues in #34

Hi,
I am having the same issue, and although I followed the various steps above it will not start.
