weird default applications behaviour

[murmel]

When installing multiple packages at the same time, which manipulate the default applications settings in the gnome control center, not all are being added and/or others are getting removed/forgotten. (a lot of times, I have the issue that the mime text/calendar is getting forgotten by gnome)

so the workaround right now is to install packages one after the other to get the option to select the correct application.

if there is a way to supply logs, I would be happy to provide them.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.

At a minimum, we need:

1. The specific steps or actions you took that caused you to encounter the problem.
2. The behavior you expected.
3. The behavior you actually encountered (in as much detail as possible).

Please also ensure that you include the release and flavour of Ubuntu that you are using.

Thank you!

could you give an example of calendar software which isn't listed by GNOME? The UI should just pick any installed .desktop, how they are installed and in which order shouldn't lead to different results

[murmel (murmel0)]

I have a script which installs all the packages I need, which includes gnome-calendar and evolution. It always shows both when installing seperately. When installing both at the same time, it can (weirdly enough, this doesn't always happen) remove one or the other, including the mime type (which makes the events in the notification center unclickable). This also happens with Music and Video (for Music I have Rhythmbox, but it clashes with mpv)(for Video it's Celluloid, mpv and Totem)

[Sebastien Bacher (seb128)]

so the calendar selector in setting doesn't list evolution or gnome-calendar in those cases? Are they listed if you right click on an ics file from nautilus?

could you include your /usr/share/applications/mimeinfo.cache in that case and the log from the packages installation?

does doing
$ sudo update-desktop-database
resolve the issue?

[murmel (murmel0)]

sadly enough, I can't reproduce this in a VM, but for some reason I had this bug in 6 out of 8 installs (on actual hardware).

So I guess I need to wait till I will have to reinstall or it was patched by accident

[murmel (murmel0)]

interestingly enough, just upgraded to kinetic, where some of the applications got removed from the list (chromium from browsers (only firefox is there), and in video only celluloid is shown.

sudo update-desktop-database does not help.

[Sebastien Bacher (seb128)]

the cache has 'text/calendar=org.gnome.Calendar.desktop;org.gnome.Evolution.desktop;', what is settings listing as calendar options for you?

[murmel (murmel0)]

only Evolution right now

[Sebastien Bacher (seb128)]

do you get any warning on the stdout/err? it's a bit of a weird issue...

[murmel (murmel0)]

no, otherwise I would have added it.

[Sebastien Bacher (seb128)]

And what's the output of

$ gio mime text/calendar

?

[murmel (murmel0)]

$ gio mime text/calendar
Default application for “text/calendar”: org.gnome.Calendar.desktop
Registered applications:
        org.gnome.Calendar.desktop
Recommended applications:
        org.gnome.Calendar.desktop

[Sebastien Bacher (seb128)]

interesting since your cache has
text/calendar=org.gnome.Calendar.desktop;org.gnome.Evolution.desktop;

it also shows the issue is at the glib level and not in the settings

could you share the output of that one?

$ for f in `strace -e openat gio mime text/calendar 2>&1 | grep mimeinfo.cache | grep -v ENOENT | sed 's/.*"\(.*\)".*/\1/'`; do echo $f; grep text/calendar $f; echo -e ''; done

[murmel (murmel0)]

$ for f in `strace -e openat gio mime text/calendar 2>&1 | grep mimeinfo.cache | grep -v ENOENT | sed 's/.*"\(.*\)".*/\1/'`; do echo $f; grep text/calendar $f; echo -e ''; done
/usr/share/ubuntu/applications/mimeinfo.cache

/usr/share/applications/mimeinfo.cache
text/calendar=org.gnome.Calendar.desktop;

/var/lib/snapd/desktop/applications/mimeinfo.cache

[Sebastien Bacher (seb128)]

hum, but

/usr/share/applications/mimeinfo.cache
text/calendar=org.gnome.Calendar.desktop;

doesn't match the content of the /usr/share/applications/mimeinfo.cache file you attached earlier in the bug... did you attach the wrong file or do config changes in between?

[murmel (murmel0)]

verified again, it's the same file. no changes in between

//edit: also looking around why chromium doesn't show up as an option. but seems like chromium isn't defined anywhere as an option. (using the snap, same as firefox)
