I attempeted to install the portable version of
texlive (on an SSD card) on a Linux Debian installation. It started OK, with some files and directories installed, but then error messages:
Installing [0001/3701, time/total: ??:??/??:??]: 12many [376k] tar: tex/latex/12many/12many.sty: Cannot change ownership to uid 0, gid 0: Operation not permitted tar: tlpkg/tlpobj/12many.tlpobj: Cannot change ownership to uid 0, gid 0: Operation not permitted tar: Exiting with failure status due to previous errors
I was doing this as
sudo, so permissions should not have been a problem. Also,
12many.sty was installed with ownership
"rw" for me and
"r" for others.
