I have texlive (version 2023) on Linux Mint. When I try to install a package using tlmgr install sidecap it says I need to update tlmgr first. I used tlmgr update --self but that returns:

Unable to download the checksum of the remote TeX Live database,
but found a local copy, so using that.

You may want to try specifying an explicit or different CTAN mirror,
or maybe you need to specify proxy information if you're behind a firewall;
see the information and examples for the -repository option at
https://tug.org/texlive/doc/install-tl.html
(and in the output of install-tl --help).


tlmgr: package repository https://mirror.niser.ac.in/ctan/systems/texlive/tlnet (not verified: unknown)
[1/1, ??:??/??:??] update: texlive.infra [345k] (66512 -> 66822) ... TLPDB::_install_data: downloading did not succeed (download_file failed) for https://mirror.niser.ac.in/ctan/systems/texlive/tlnet/archive/texlive.infra.tar.xz
tlmgr: Installation of new version of texlive.infra failed, trying to unwind.
tlmgr: Restoring of old package did NOT succeed.
tlmgr: Error message from unpack: don't know how to unpack
tlmgr: Most likely repair: run tlmgr install texlive.infra and hope.
done
tlmgr: The file README has disappeared from the critical package texlive.infra but is still present in dehyph:texmf-dist/tex/generic/dehyph/README dvipdfmx:texmf-dist/fonts/cmap/dvipdfmx/README mfware:texmf-dist/mft/base/README texlive-scripts:texmf-dist/fonts/map/dvips/tetex/README
tlmgr: action update returned an error; continuing.
tlmgr: package log updated: /home/fes33/.TinyTeX/texmf-var/web2c/tlmgr.log
tlmgr: An error has occurred. See above messages. Exiting.

Reading some of the other queries I gathered that it's because the mirror niser.ac.in/ctan/systems/texlive/tlnet isn't working. I tried the solutions here but it didn't work:

(running on Debian, switching to user mode!)
(see /usr/share/doc/texlive-base/README.tlmgr-on-Debian.md)
TLPDB: not a directory, not loading: /root/texmf
tlmgr: user mode not initialized, please read the documentation!

What else can I do?

  • Neither log appears to be from an upstream installation from https://tug.org/texlive/ how have you installed TeX Live? I'm not certain but sounds like the first is a local TinyTeX installation (via R?) and the second (on sudo path) is an apt-installed. If you installed from the OS package manager that is how you should update TeX Live, OS-packaged TL distros generally aren't capable of allowing finer-grained management of the TL distribution through tlmgr. They also separate the full TeX Live into a few different apt-packages (https://tex.stackexchange.com/a/504566/106162). – Dai Bowen Sep 09 '23 at 12:30
  • Yes, I've been using R Markdown and Quarto and use it to render pdf. I also installed Tex Studio so I think the other one comes from that. – R Walser Sep 09 '23 at 13:02
  • OK, installing TeXStudio via the OS package manager has installed another distro as a dependency, this one comes up first in the super user's PATH while the TinyTeX is first in your own PATH. Did you try running tlmgr install texlive.infra as the first error message suggests? – Dai Bowen Sep 09 '23 at 13:39
  • Can you try updating tinytex via R? – Dai Bowen Sep 16 '23 at 20:19
  • Yes but the documentation says that TinyTex is supposed to install missing packages on the fly. – R Walser Sep 17 '23 at 00:33
  • I have the same problem to use tlmgr on Mint today. Any idea what is going on? – Sigur Nov 17 '23 at 02:34
