Warning: unable to load shared object 'R_X11.so': libXt.so.6: cannot open shared object file

I got constant warning:

Warning message: In grSoftVersion() : unable to load shared object '/usr/local/lib/R/modules//R_X11.so': libXt.so.6: cannot open shared object file: No such file or directory

I also wanted to fix maybe the issue with solution I found somewhare - apt-get install -y --no-install-recommends libxt6, but I couldnt find the sudo password to do this in the terminal in Rstudio?
