dmesg shows stranges massages. Last year I tried mythtv but it didn't work for me and thus I removed it again.

Today I saw that dmesg shows this messages:

[   16.047679] init: mythtv-backend main process (2489) terminated with status 127
[   16.047707] init: mythtv-backend main process ended, respawning
[   16.060100] init: mythtv-backend main process (2503) terminated with status 127
[   16.060124] init: mythtv-backend main process ended, respawning
[   16.071027] init: mythtv-backend main process (2514) terminated with status 127
[   16.071061] init: mythtv-backend respawning too fast, stopped

But mythtv is definitely not installed

~$ dpkg --get-selections | grep mythtv
mythtv-backend                  deinstall
mythtv-common                   deinstall
mythtv-database                 deinstall
mythtv-frontend                 deinstall
mythtv-transcode-utils              deinstall

This post seems to solve a similar problem (with juju instead of mythtv). Obviously the corresponding remedy would be to delete /etc/init/mythtv-backend.conf

Can I do so safely? Is there anything else I can/should do (maybe similar to running stop juju-jon-sample-file-storage in the previous mentioned post)?

What's the output of file /etc/init.d/mythtv-backend /etc/logrotate.d/mythtv-backend && sudo updatedb && locate mythtv? (The middle part may take a while after you put in your password, that's OK.) – Eliah Kagan Jan 29 '13 at 11:45
I can't give that a shot anymore since I already purged everything. Thanks anyway – justfortherec Jan 29 '13 at 13:00
That's OK--there's no need to investigate where the files are if you were able to remove them. – Eliah Kagan Jan 29 '13 at 13:04

dpkg --get-selections should return nothing for packages that are not installed. The fact that it is returning something is a symptom that there are parts of the package that have not been removed.

If you try --list instead of --get-selections, you'll see the reason why the package is not fully removed. In your case, you should see rc near mythtv-backend, meaning that there is still Residual Configuration for the package.

Files inside /etc are considered configuration files and are not removed automatically when removing a package. To remove residual configuration, you need to purge the package:

apt-get purge mythtv-backend

This is the correct way of removing all configuration files, including the ones in /etc/init.

Oh Thanks. I only tried apt-get purge mythtv which obviously didn't work. No everything is fine. Thanks – justfortherec Jan 29 '13 at 13:00
