Trigger high-color-icon-theme takes minutes with every install

[Florian R,]

Whenever "trigger high-color-icon-theme" is called while installing some app with gui, this can take up to 6 minutes!

I think, there's some timeout running, so how can i improve this?

You mean hicolor-icon-theme?

Please paste the actual output from when the process hangs and also
the output of:

 $ sudo grep hicolor-icon-theme /var/lib/dpkg/{info/*.triggers,triggers/*}

 status incomplete

# grep hicolor-icon-theme /var/lib/dpkg/{info/*.triggers,triggers/*}
/var/lib/dpkg/triggers/File:/usr/share/icons/hicolor hicolor-icon-theme

What exactly do you miss? Last point has been the grep, right?

This is still the case on two machines here with 12.04 precise, unfortunately

Changed status to reflect it isn't solved

That is, all output from “apt-get install foo” onwards. Use apt-get, not aptitude to reproduce.

In addition to providing the previously requested information, you can flesh out your initial claims:

Give concrete examples of packages that approx. 6 minutes at this step. Do some packages pass this step much faster?

What type of filesystem is /usr?

What makes you think that?

Well, basically only the time, no technical idea. As it is taking soo much time and CPU is low, i would expect some timeout the script is waiting for, perhaps some missing folder issue or whatever... i am just guessing.

Is there a way how i can run this trigger in some kind of debug mode for having logging messages?

"aptitude upgrade amarok" yesterday. Took more this time, approx. 10 minutes.

Just giving it a try, am upgrading...will give feedback soon

Ok, CPU (both!) are at 100% while the trigger is running, so it's perhaps noting with some timing.

Following the results for "kdf" (Trigger running from 19:39h to 19:53h: 14 minutes!):

The trigger executes only one command, you can invoke it manually without --quiet to see if it behaves similar:
# gtk-update-icon-cache --force --quiet /usr/share/icons/hicolor

(and/or gtk-update-icon-cache-3.0)

[Daniel Hartwig (wigs)]

The delay here might not be due to any bug at all. Reassigned to gtk+ packages for their maintainers to determine.

Florian, which version of libgtk2.0-bin and libgtk-3-bin are you using?

[Florian R, (xyz)]

2.4.24.10-0ubuntu6 and 3.4.2-0ubuntu0.5?
