When I try to install packages on MRAN version 4.0.2 through Rstudio server 1.4.1103 on Ubuntu 20 I get this message:
unable to access index for repository https://mran.microsoft.com/snapshot/2020-07-16/src/contrib:
cannot open URL 'https://mran.microsoft.com/snapshot/2020-07-16/src/contrib/PACKAGES'
Despiste the commands works fine when I open MRAN through the terminal. Any help on this issue??
