Hi Jackow,
Thank you for taking the time to report this bug and helping to make Ubuntu
better.
first as it might be interesting to you in general you might run
$ aptitude why postfix
This should help to understand by which dependency (chain) this is now
installed.
If the discussion on the bug goes on reporting here would also be nice.
>From the Log:
newaliases: fatal: file /etc/postfix/main.cf: parameter setgid_group: group
postdrop has same group ID as mlocate
I think that is the root cause.
There was a similar issue and some analysis a long long time ago in bug 378955
But no other report I heard of.
Is there something special to your mlocate setup?
To be sure please report back with
$ id mlocate
$ id postdrop
But much more IIRC this belongs to the setuid on newaliases.
newaliases is a symlink and depending on your current mailer points to
something else, for example:
$ ll /usr/sbin/newaliases
lrwxrwxrwx 1 root root 5 Apr 13 2016 /usr/sbin/newaliases -> ssmtp*
In your case likely from postfix.
Please check the target of that link and report it here:
$ ls -laF $(readlink -f /usr/sbin/newaliases)
And since these are groups not users you might want to check with
$ getent group <groupname>
Use as groupname
1. mlocate
2. postdrop
3. whatever is the group of the link you checked above
Since it seems likely to me that this is a local configuration problem,
rather than a bug in Ubuntu, I'm marking this bug as Incomplete.
If you expect this to be a bug in Ubuntu please provide the inquired
information and set it back to status new.
** Changed in: postfix (Ubuntu)
Status: New => Incomplete
