I am trying to get LaTeX working on a fresh Ubuntu 18.04 installation. When I install
apt-get, I get an extremely minimal (and insufficient) set of packages (not even Tikz!). Trying to install
texlive-full brings up a bunch of errors about not being able to connect to certain repos, so I also gave up on that.
I have now installed TeXLive 2018 from TeXLive's website, as I understand this is the recommended way to install it for Ubuntu. However this installation still does not contain all the packages I need. I have tried installing the package
tlmgr to get the packages I need, and (after already fixing some errors), I get the following message:
tlmgr: Remote repository is newer than local (2017 < 2018)
How can this even be the case, when I installed TeXLive 2018, and now how can I fix this? Any help would be greatly appreciated, as I've been bashing my head against getting LaTeX working for half a week now.
