I am looking for a solution. I know that packages can be downloaded from CTAN, but I never realized where to put the files to install them. I am using TeXmaker 5.0.2, but I don't know exactly where it looks for libraries and required files to run.
The exact prompt of the message goes as follows:
/usr/share/texlive/texmf-dist/tex/latex/base/fontenc.sty >>>>
Package fontenc Error: Encoding file `ot2enc.def' not found
/usr/share/texlive/texmf-dist/tex/generic/babel/babel.sty >>>>
! Package babel Error: Unknown option `russian'. Either you misspelled it(babel) or the language definition file russian.ldf was not found.See the babel package documentation for explanation.Type H <return> for immediate help.... \ProcessOptions
