Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

pycompile is provided by python-minimal; as this is a direct dependency of python-decorator I can only assume a local change was made to the system to remove this binary - please can you check its present and if not:

  sudo apt install --reinstall python-minimal

Marking this bug as 'Invalid' as its not specific to this python module.
