I have installed Texlive 2021 on Ubuntu 21.04 on a new laptop. There aren't previous version of Texlive in the system. I have had to install it as root user since, while trying to install it as simple user he didn't let the installer write in some directories.
Following, the guide I have updated the paths in the
$HOME/.profile file adding the following expressions:
if [ -d "/usr/local/texlive/2021/bin/x86_64-linux" ] ; then PATH="$HOME/usr/local/texlive/2021/bin/x86_64-linux:$PATH" fi if [ -d "/usr/local/texlive/2021/texmf-dist/doc/man" ] ; then MANPATH="/usr/local/texlive/2021/texmf-dist/doc/man:$MANPATH" fi if [ -d "/usr/local/texlive/2021/texmf-dist/doc/info" ] ; then INFOPATH="/usr/local/texlive/2021/texmf-dist/doc/info:$INFOPATH" fi
This way Latex works fine.
tlmgr, in root mode, I can open and operate the GUI.
I tried, still in root mode (in user mode ir says I have to run it in root mode)
tlmgr update --self (and > tlmgr update --self)
It gave me the following message:
(running on Debian, switching to user mode!) (see /usr/share/doc/texlive-base/README.tlmgr-on-Debian.md) TLPDB: not a directory, not loading: /root/texmf tlmgr: user mode not initialized, please read the documentation!
I tried to employ
--usertree with no success.
Finally I wrote
PATH=/usr/local/texlive/2021/bin/x86_64-linux:$PATH; export PATH MANPATH=/usr/local/texlive/2021/texmf-dist/doc/man:$MANPATH; export MANPATH
INFOPATH=/usr/local/texlive/2021/texmf-dist/doc/info:$INFOPATH; > export INFOPATH
This way it works. Any alternative, that saves me copying and pasting those instruction? When writing
echo $PATH echo $MANPATH echo $INFOPATH
the terminal lists the corrects directories. What's missing? I think I should set a PATH, but where?
UPDATE! (partially solved but not quite)
I copied the $PATH, $MANPATH, $INFOPATH on the .basch file. Now
tlmgr update -all
works fine Unfortunately
tlmgr update --self
responds this way.
tlmgr: Local TeX Live (2020) is older than remote repository (2021). Cross release updates are only supported with update-tlmgr-latest(.sh/.exe) --update See https://tug.org/texlive/upgrade.html for details.
I have tried to follow the suggestions on the upgrade page of tug.org/texlive without success.
