Re: texlive2025, TeXstudio, reinstallation

Axel, success!!

As far as I could I rid myself of the previous install, then,
I installed re-installed TeXLive according according to 
www.tug.org/texlive/quickinstall.html using the -gui option so I could see
all those possibilities. I chose paper=letter, scheme=full and off it 
went getting 4940 files.

Line 3 -4 if install-tl.log read:
Loading 
https://ca.mirrors.cicku.me/ctan/systems/texlive/tlnet/tlpkg/texlive.tlpdb
Installing TeX Live 2025 from: 
https://ca.mirrors.cicku.me/ctan/systems/texlive/tlnet (verified)

Having had previous experience of the repositories for TeXstudio 
installing its own, partial texlive, I got the 4.9.0
via the ppa on code.launchpad.net/~sunderme/+archive/ubuntu/texstudio

Then tried to hook the two together and failing.

But back to SUCCESS, for which I am your debt. I looked at your image in 
TeXworks_preferences.png,
added (by +) the /usr/local/texlive/2025/bin/x86_64-linux directory, 
used up-arrow to move it to the top,
clicked OK, loaded the test file, hit the green > and, VOILA!, the 
desired result.

Went to a larger test and all went well there too.

I'm used to tabbed files to edit, but that can come (possibly) as I look 
further in preferences.

I already has that directory in a $PATH item in TeXstudio - no luck.

I see your ^^^ above . The head of the log for the larger test is :
<snip>
This is pdfTeX, Version 3.141592653-2.6-1.40.28 (TeX Live 2025) 
(preloaded format=pdflatex 2025.11.24)  24 NOV 2025 20:32

**TEST-LinalgDRv25DEC2017.tex
(./TEST-LinalgDRv25DEC2017.tex
<snip>
no mention of Debian now!

and googled for install texlive not the Debian package. That pointed me 
to get the installer from
mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz

The method I used from  www.tug.ord/texlive/quickinstall.html (above) 
pointed me at
mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz

which is exactly the same as immediately above.

Many, many thanks for your help so far

Cheers
Greg
