package iptraf 3.0.0-7 failed to install/upgrade: package iptraf is already installed and configured

[Yang]

Binary package hint: dpkg

I don't know what caused this. sudo iptraf seems to run fine.

I had installed iptraf earlier in the day, then rebooted my computer. After the reboot, that's when I noticed the exclamation mark/exploding star icon in the tray (it may have been there earlier).

Thanks for your bugreport.

Could you please attach /var/log/apt/history.log ?

Here you go. This was generated with:

cd /var/log/apt/
for i in 10 9 8 7 6 5 4 3 2 1 ; do zcat history.log.$i.gz ; done | cat - history.log | gzip > /tmp/history.log.gz

Thanks a lot for this data!

Here is where the error happend:

Start-Date: 2011-01-04 11:04:44
Install: nethogs (0.7.0-3)
Error: Sub-process /usr/bin/dpkg returned an error code (1)
End-Date: 2011-01-04 11:04:59

What is confusing in the terminal log is that apparently apt wanted to configure iptraf but there
is nothing in the logs that indicate that it needs configuring (i.e. the previous operation seems
to have completed just fine):

It looks like it was a one-time-only-error, right? I.e. it did not hapen on the subsequent runs of apt?

One possible explaination could be that the man-db trigger lead apt to believe that the iptraf package needs configuration. This would explain why it was a one-time-only issue (if it was one) as the subsequent nethogs install activated the trigger and caused the problem to go away.

Yeah I guess it never came up again...
