R-4.0.0 and Texlive 2020 installed on EmmabuntusDE4 (Debian Bullseye)

Hi Johannes,


Thank you for your comments. I run
   sudo apt install -t bullseye-cran40 r-base

and have now the current R-4.0.0 in /usr/lib/R with links in the menus
and R-devel R-4.1.0 in ~/patrice/svn/R/r-devel/build. Perfect.

I used sid just to get the full Texlive 2020. I will probably not update
it for a while and have already removed (commented) the sid line in
sources.list as I do not want to break my system with too much fresh
libraries. Indeed, we want to be on the edge for a few software (R,
Texlive) and are conservative for all other parts of the OS. Thanks for
the tips on /etc/apt/preferences.

Regarding the key, you can probably move the section at the top of the
documentation as it is a necessary step. The key currently mentionned in
the instruction is:
  sudo apt-key adv --keyserver keys.gnupg.net --recv-key
'E19F5F87128899B192B1A2C2AD5F960A256A04AF'

but the one that worked for me (found in one comment in
https://stackoverflow.com/questions/10255082/installing-r-from-cran-ubuntu-r
epository-no-public-key-error) is:
  sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys
  FCAE2A0E115C3D8A

The length of digits is different. Maybe one is the shortest version of
the other?

Dear Patrice,


thanks for sharing your experience with Debian based distributions. It
is amazing how many distros you tested!

In your situation I would recommend apt pinning for installing texlive
2020 from Debian sid on Debian bullseye aka testing or related systems.
Simply adding sid sources as you did will make your system upgrade to
sid. It seems you partially upgraded some of your test systems to sid
and were left with broken systems.

This will also apply to emmabunt? - if you just added the sid repository
without editing /etc/apt/preferences, you will always pull packages from
sid which may be ok for your use case, but you should be aware of it.

You would need to edit /etc/apt/preferences in order to tell apt to just
use texlive from sid and the other packages from bullseye.

Regarding the command to add my key, this is actually there, but I
believe it was too far down - I just moved the section on secure apt
before the section on the different distributions. Thanks for the hint!

Regarding your attempt to use the backports for bullseye on CRAN for
your Emmabunt?s system, chances are it would have worked if you would
have used the command I am listing there (of course adding sudo):

   sudo apt install -t bullseye-cran40 r-base

instead of simply

   sudo apt install r-base

However, now you have the newest devel version compiled from sources for
checking your packages on Linux which is nice as well!


Kind regards,


Johannes
