The following code

documentclass{article} 

usepackage{lipsum}



begin{document} 

lipsum 

end{document}

all of a sudden gives the following error in TexStudio on Ubuntu 18.04 with TexLive:

File `lipsum.sty' not found. usepackage

BUT, I can successfully compile from bash:

$ latex top.tex

I'm thinking this might be because I removed LatexDraw using:

apt-get remove --purge latexdraw

apt-get autoremove

I've tried debugging this, so I list the outputs of some of the commands I ran:

• 
  which tex gives /usr/local/texlive/2018/bin/x86_64-linux/tex
  


• 
  kpsewhich -var-value=TEXMFHOME gives /home/me/texmf, a non-existing directory
  


• 
  kpsewhich lipsum.sty gives /usr/local/texlive/2018/texmf dist/tex/latex/lipsum/lipsum.sty
  


• Inside TexStudio, Build/Commands ($PATH) reads /usr/local/texlive/2018/bin/x86_64-linux
  

Any help is appreciated!

I restarted my computer and it went back to working normally. 10 minutes later, the problem is back...

Once again, the solution is: restart your computer. Anyone who has a real solution or followup is welcome to post an answer.
