update-alternatives: attention: there is no alternative / 5sr / b) n'python3-pbr (part of the group of links pbr); eliminating it from the list of alternatives
update-alternatives: error: / var / lib / dpkg / alternatives / pbr corrupted: end of unexpected file when trying to read master file

[James Page (james-page)]

It looks like the alternatives db for pbr has become corrupted, hence the package won't install/updated

[James Page (james-page)]

I think this is an install local issue - you should be able to resolve using:

  sudo update-alternatives --remove-all pbr
  sudo rm -f /etc/alternatives/pbr /var/lib/dpkg/alternatives/pbr
  sudo apt install --reinstall python3-pbr
