biblatex option: bbx file cant be found about lni HOT 13 CLOSED

You have to install the package biblatex-lni. If it is not available via your TeX distribution you can get it from CTAN.
Copying the files .bbx, .cbx and .lbx into your document's directory is sufficient. However, an installation into your local TEXMF tree is preferable.

Maybe there could also be a reference in the README for this. (In my case I move all the relevant file to paper-repo so all dependencies are shipped to all collaborators, making them install all the stuff would rise the barrier for collaboration ;-) )

I think this is related to the same issue, because now since I've copied over these three files I get the following errors:

! Package xkeyval Error: `giveninits' undefined in families `blx@opt@pre'.

See the xkeyval package documentation for explanation.

Seams to be a problem with my biblatex version: https://tex.stackexchange.com/questions/316377/biblatex-no-author-year-delimiter-for-one-literature-type#316380

from lni.

Yes, it is.
Please read the requirements for biblatex-lni:
It re­quires at least bibla­tex 3.5 and biber 2.6.

from lni.

There was a critical change in the way names are handled. Therefore older versions of biblatex will have to be supported separately.

Hi,
I am getting the following error:
! Package biblatex Error: Style 'LNI' not found.

I have copy pasted the cbx, lbx etc files in the texmf tree, still the error persists. can you help?

Thank you

from lni.

It should not be necessary to manually install the biblatex files. If you have a not too old MiKTeX or TeX Live please install biblatex-lni with the package manager.

If you still want to install it manually don't forget to update your database with texhash

I installed texlive 2020, and biber was 2.14 which I could not be updated to 2.6 which I downloaded from sourceforge, again installed texlive-full and this again 2015 version, and tlmgr seems does not work with 2015. I try to indstall tlmgr biblatex-lni and I get this error "tlmgr install: package biblatex-lni not present in repository. tlmgr: action install returned a warning."
With synaptic package manager and apt-cache, there is no package with name biblatex-lni, please help

from lni.

Installing TeX Live 2020 is fine. Please do not mix old stuff. Biber 2.6 is older than 2.14 and should not be used! Stick to your installation. If you installed a full version, everything is there.
If your problems persist, please add an minimal working example and your log file.

from lni.

Ok, thanks. The command line compilation works fine, it can generate my pdf with citation entries correctly. I use the following commands at the command line pdflatex main and then biber.main and then again pdflatex main. However, when I run it through texmaker it gives me following error as attached.

main.log

from lni.

Are you compiling the exact same file on the command line and in TeXmaker? When does the error occur? Right at the first run? Is TeXmaker configured to run biber?
Could you please try to run a minimal example and post the file here as well?

from lni.

Yes, I have changed Texmaker setting accordingly. I actually took your MWE example that I downloaded from the CTAN. That again from command line works fine, but with Texmaker it generates errors. see the attached image which contains the error and MWE.

There is something very wrong going on with your installations ... Your log file says TeX Live 2015 and uses some pdflatex format from 2020

Please remove the old TeX Live 2015 completely and only use the up-to-date 2020 version. You can also try to set another path (or just "pdflatex") in TeXmaker to really use the TL 2020 binaries. I guess that is the difference between command line and gui.
