I'm on Ubuntu 20.04. R version 4.0.2. I've been using R for a long time and everything worked fine. Today, when trying to install new packages i get this error:
** checking absolute paths in shared objects and dynamic libraries
readelf: symbol lookup error: readelf: undefined symbol: ctf_arc_bufopen, version LIBCTF_1.0
Error in system(paste("readelf -d", shQuote(l)), intern = TRUE) :
error in running command
I tried to delete and reinstall R and all the packages, but now the same thing happens also for packages that were previously installed. So i think that the problem is not caused by R itself. I havent done any R update recently.
