[Bug 629234] Re: package vsftpd 2.2.2-3ubuntu6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Scott Moser]

Imre,
  You're right.  What we really should do is
a.) open a new bug against vsftp in natty regarding the issue mentioned in comment 12.
b.) forward that bug to debian, with appropriate patch against debian

Then, we should apply that patch here.
We could then close this bug and request that one be SRU'd to hardy.  I would think , though, it would be sufficient to simply fix hardy correctly under this bug.

Title:
  package vsftpd 2.2.2-3ubuntu6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Status in “vsftpd” package in Ubuntu:
  Fix Released
Status in “vsftpd” source package in Lucid:
  In Progress
Status in “vsftpd” source package in Maverick:
  Fix Released

Bug description:
  Binary package hint: vsftpd

I am not sure what to put here other then I am running Ubuntu 10.04 on a laptop. Ubuntu stated that it failed to install the package except that the vsftpd server is running fine. I connected with out a problem. I even went into the config file and
changed a setting then restarted the service. It appears to be running correctly. After making the change and restarting
the service I connected locally from my desktop to the ftp server with no problems. Even transfered several files. Then I noticed
the star shaped exclamation point on the task bar and now I am writing this..

Let me know if you need any more information such as specs of the machine. What I said above covers what I was doing/working on when the message appeared.

=======
SRU Justification

IMPACT: This bug affects users installing vsftpd (see the numerous duplicate bugs).

REPRODUCE: Have an "ftp" user on your system, but no ftp group.  Try installing the vsftpd package.  Boom.

HOW FIXED: The logic in the postinst needs to be rearranged slightly.  First check if the group exists, if not, add it.  Then check if the user exists, if not add it to to the group.

PATCH: Attached.  Uploaded to lucid-proposed for review there.

REGRESSION POTENTIAL: Minimal.  I've tested the installation thoroughly.  The new method is idempotent.
