I was working for weeks in the latest Rstudio running on the latest R base 4.2.1 on Linux Mint 20.0 Ulyana (Ubuntu Focal) all updated, during those weeks I occasionally rebooted the system and all was good. Yesterday the power went down and I booted back on R would give me this R not found window: "R shared library (/usr/local/lib/R/lib/libR.so) not found. If this is a custom build of R, was it built with the --enable-R-shlib option?"
There are several identical topics discussed and closed already on https://forum.posit.co/, however, none of the solutions helped me so far, perhaps I'm just overlooking something. I guess force move libR.so will just create yet another problem. And as of was R built with the --enable-R-shlib option? I don't know, can it just be overwritten to enable it?
i can completely remove and successfully reinstall R base 4.2.1 from tarball and as instructed by r-project.org, but I still get the same unable to initialize the JIT error even though I uninstalled and reinstalled also the Rstudio too. Resetting RStudio desktop's state as described here didn't help either.
