I try to install the pdflscape package from ctan using the r package tinytex.
Running tinytex::tlmgr_install("pdflscape.sty") produces the following error:
TLPDB::from_file could not initialize from: http://ctan.mines-albi.fr//tlpkg/texlive.tlpdb
In my organization, I usually have to use a proxy, for example using httr::set_config(httr::use_proxy()) but this did not solve the problem.
Any help is appreciated!
