Could you repost the /var/log/dist-upgrade/ content? It apparently got truncated to 40bytes...

Added content of /var/log/dist-upgrade

newaliases: fatal: file /etc/postfix/main.cf: parameter setgid_group: group postdrop has same group ID as winbindd_priv

Do you have any idea how these two groups might have goten the same group ID?

[valle (simtec)]

I have no idea. I am sure that I never created any group manually on this computer. As far as I remember I did a fresh install on Ubuntu 8.10 and upgraded to 9.04. Thanks a lot to care for this problem.

[Andreas Olsson (andol)]

sounds strange. You don't happen to (also) use an external source such as NIS och LDAP for your user information? Can you give me the output of these two commands?

$ getent group | egrep "postdrop|winbindd_priv"
and
$ ls -la /etc/postfix/

[valle (simtec)]

Please excuse the late response.

 * I don't use LDAP (as far as I know)
 * I use NFS + NIS (client)

As far as I see everything works fine after the upgrade. As I use evolution for emails postfix is probably not used on my client computer. Seems that /etc/postfix has not been created.

$ getent group | egrep "postdrop|winbindd_priv"
winbindd_priv:x:124:
postdrop:x:124:

$ ls -la /etc/postfix/
ls: Zugriff auf /etc/postfix/ nicht möglich: No such file or directory

$ sudo ls -la /etc/postfix/
[sudo] password for vb:
ls: Zugriff auf /etc/postfix/ nicht möglich: No such file or directory

[Andreas Olsson (andol)]

Yes, now I believe I know where the problem originates. If you resolve your gid conflict between your local /etc/group and your yp group map I'm pretty sure postfix will install just fine.

[valle (simtec)]

I finally found some time to proof your assumption. Thanks a lot for the help!

[Andreas Olsson (andol)]

@valle: Glad to hear you got postfix installed properly.

Marking this bug as Invalid. I don't think we can blame Postfix for being confused by gid conflicts :)
