CondaVerificationError: The package for llvm-openmp located at /home/bla/anaconda3/pkgs/llvm-openmp-14.0.4-he0ac6c6_0
appears to be corrupted. The path 'lib/libarcher.so.bak'
specified in the package manifest cannot be found.

I manually downloaded and unzipped the conda package once and there I could see the supposedly missing file. With version 8, for example, the installation works, but that is not enough for me. I am also sure that I had installed this package before the last Ubuntu update, then I had to reinstall the graphics driver among other things. I am using Ubuntu 22.04.1 LTS.

CodePudding user response：

The fact that the package is not listed in the downloads section of the transaction summary, implies that it is in the package cache and it is corrupted there. Try removing both the tarball (tar.gz and/or .conda) and the corresponding unbundled folder from the package cache. One can query the package cache location(s) with

conda config --show pkgs_dirs
## probably something like
## /home/bla/anaconda3/pkgs

and remove whatever has llvm-openmp-14.0.4-he0ac6c6_0.
