Fresh install of TeXLive 2021 didn’t set system variables Linux

texliveupdate

After installing texlive2021 I noticed that "tex" still referred to the 2020 version which I have removed after installing texlive2021.
I thought a restart would help, but now it just offers me to install texlive-binaries using the package manager.

I am thinking about purging everything and reinstalling, but I thought I might ask here first.
Commands no longer working are:

tex, pdftex, latex, xetex, xelatex, kpsewhich, tlmgr

/usr/local/texlive/ contains 2021 as expected.

The installation instructions explictly say that you need to set the PATH after the install.

A solution is to build Kile from source. After doing so it works perfectly with TeXLive2010

The problem lies in the fact that you chose to create symbolic links for the executables in /usr/local/texlive/2011/bin/<architecture> to /usr/local/bin.

With tlmgr there's the possibility to update them, but the action is not performed automatically.

However, my advices are:

Always install the full TeX Live
Never create symbolic links, particularly on Debian based systems

If you don't have strict space constraints, do a full TeX Live install. It would have avoided the problem of installing the XeTeX subsystem.

Changing what's in /usr/local/bin is dangerous as other system utilities may choose to install something there. It's better to change the PATH variable and the safest method is to write a file zzz-texlive.sh containing

export PATH=/usr/local/texlive/2011/bin/`uname -i`-linux:$PATH
export MANPATH=/usr/local/texlive/2011/texmf/doc/man:$MANPATH
export INFOPATH=/usr/local/texlive/2011/texmf/doc/info:$INFOPATH
unset TEXINPUTS
unset TEXMFCONFIG

and move it into /etc/profile.d. After a logout/login cycle, the PATH variable will contain the correct directory for the executables.
