+AD4 +AD4 So I started over (restored snapshot) and then tried adding a ppa apt source which contains 2.1.29:

+AD4 +AD4 
+AD4 +AD4 Installed with an IO error over a lock file purported to be from one of my lists but otherwise started ok. But sending an email produced an error complaining:
+AD4 +AD4 
+AD4 +AD4 The mail system
+AD4 +AD4 
+AD4 +AD4 +ADw-list+AEA-localhost+AD4: Command died with status 2: +ACI-/var/lib/mailman/mail/mailman
+AD4 +AD4  post list+ACI. Command output: Group mismatch error. Mailman expected the
+AD4 +AD4  mail wrapper script to be executed as group +ACI-daemon+ACI, but the system's mail
+AD4 +AD4  server executed the mail script as group +ACI-list+ACI. Try tweaking the mail
+AD4 +AD4  server to run the script as group +ACI-daemon+ACI, or re-run configure, providing
+AD4 +AD4  the command line option +AGA---with-mail-gid+AD0-list'.

+AD4 This is a group mismatch in the /var/lib/mailman/mail/mailman wrapper.
+AD4 See +ADw-https://wiki.list.org/x/4030645+AD4 for more on group mismatch.
+AD4 
+AD4 This may be an issue with the ppa which is maintained by +AEA-jimpop who
+AD4 reads this list and may chime in.
+AD4 
+AD4 However, Postfix is running the wrapper as group 'list' because 'list'
+AD4 is the owner of Mailman's data/aliases.db file. You can change this by
+AD4 +AGA-chown daemon data/aliases.db+AGA but you need to ensure that that file is
+AD4 still group 'list' and group writable for Mailman to be able to update
+AD4 it as lists are added/deleted.


New PPAs were released a few hours ago that address this userid mis-
match problem.
