Webmail inbox not emptying & upgrading errors

my webmail inbox messages used to be deleted once I downloaded them to my mail client. it is no longer doing so. I’m running MIAB version 62 on Ubuntu 22.04.2 LTS.

When I upgraded MIAB from version 61.1 to 62 I received the following errors and the upgrade aborted. Could this have created the problem? thank you!

ERROR: Cannot uninstall ‘blinker’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
