[Pkg-mailman-hackers] Bug#891553: mailman3-suite: Cannot remove package

[Colin Turner]

Package: mailman3-suite
Version: 0+20170523-9
Severity: important

Dear Maintainer,

Thanks for your work on this package.

I attempted to install mailman3 but found that the service would not start and generated a lot of cron errors as a result. Efforts to configure and fix the package failed and I decided to remove it.

Unfortunately I cannot remove this package.

oldgondolin:/home/colin# aptitude -f purge mailman3-suite

Removing mailman3-suite (0+20170523-9) ...
You must invoke apache2-maintscript-helper with an unmodified environment when sourcing it
dpkg: error processing package mailman3-suite (--remove):
 installed mailman3-suite package post-removal script subprocess returned error exit status 1
Errors were encountered while processing:
 mailman3-suite
E: Sub-process /usr/bin/dpkg returned an error code (1)

I wouldn't mind testing the package again, but at the moment it's rendering the entire packaging system inoperative. As it happens this is on a server I'm decomissioning, but it's still making life more complicated.

Kind regards,

CT.
