I have been spending hours trying to read answers and blogs and I cannot understand what is the problem with my installation.
I have installed TexLive under ubuntu 18.04. I can compile latex files, make indexes etc. with no issues. I wanted to install a new package and now I am having a problem.
When I try to install the package I get the following message:
tlmgr: Remote repository is newer than local (2017 < 2019) Cross release updates are only supported with update-tlmgr-latest(.sh/.exe) --update Please see https://tug.org/texlive/upgrade.html for details.
This is puzzling as I do have TexLive 2019 installed as it shows by running
pdflatex --version (I can type this anywhere since everything is in the path):
pdfTeX 3.14159265-2.6-1.40.20 (TeX Live 2019) kpathsea version 6.3.1 Copyright 2019 Han The Thanh (pdfTeX) et al. There is NO warranty.

Anyway, I decided to follow the request to use
update-tlmgr-latest but, well, I got the following issue:
Verifying archive integrity... All good. Uncompressing TeX Live Manager Updater 100% ./runme.sh: Cannot find TeX Live root using kpsewhich --var-value=SELFAUTOPARENT. ./runme.sh: (no tlpkg/texlive.tlpdb and/or tlpkg/tlpobj/.) ./runme.sh: Please set your PATH as needed, otherwise it's hopeless.
If I run
kpsewhich --var-value=SELFAUTOPARENT I get the following result
which is the right root of the TexLive 2019. Not sure what to do exactly and now I am stuck as I am not able to install packages.
