Description Pacho Ramos gentoo-dev 2021-07-20 23:53:59 UTC 
I don't know why after updating one of my machines I am completely unable to start gdm due to errors like:


For now I have seen that, when building glib, I get:
>>> Completed installing dev-libs/glib-2.68.3-r1 into /var/tmp/portage/dev-libs/glib-2.68.3-r1/image

The errors in dmesg are like:

But the schemas are present, I have also tried to reinstall gsettings-desktop-schemas but keep failing :/

Comment 5 Pacho Ramos gentoo-dev 2021-07-21 00:21:34 UTC 
It looks similar to bug 786573, but I have all the packages at their -40 versions (even if this system is older and got updated from Gnome 3.36 instead of Gnome 3.38 to Gnome 40)

This shows that portage does not know what gentoo package provides libffi.so.7.

What does
    $ cat /var/db/pkg/dev-libs/libffi-*/PROVIDES
print on your system? What version of libffi you have installed?

I think that's unexpected. If you rebuild libffi does it come back?
Comment 9 Pacho Ramos gentoo-dev 2021-07-21 08:49:44 UTC 
After rebuilding I have it

# cat /var/db/pkg/dev-libs/libffi-3.3-r2/PROVIDES
x86_32: libffi.so.7 x86_64: libffi.so.7

QA warning is removed but, sadly, gdm and gnome keep failing to start with the glib error :(
[    9.287457] traps: gnome-session-b[776] trap int3 ip:7f5bcb1864e3 sp:7ffc9bffc0b0 error:0 in libglib-2.0.so.0.6800.3[7f5bcb148000+8d000]
Comment 10 Sergei Trofimovich (RETIRED) gentoo-dev 2021-07-21 09:18:59 UTC 
That's probably a different error. Can you get a symbolized backtrace?

int3 might be an explicit assertion failure somewhere in glib.
Comment 11 Pacho Ramos gentoo-dev 2021-07-21 09:24:16 UTC 
Rebuilding gnome-session I get a bit more far: now I get the "Oh no, something was wrong" gnome-shell screen and kernel trap affects other:
[    7.015485] traps: gsettings-helpe[749] trap int3 ip:7f2afc43ce57 sp:7ffc017ef9c0 error:0 in libglib-2.0.so.0.6800.3[7f2afc3ff000+8d000]


I will try too keep rebuilding and so and see what happens

Thanks a lot for your help!

For now I also needed to rebuild pulseaudio, after that, no more kernel traps but:

Due to missing /usr/share/glib-2.0/schemas/org.gnome.GWeather.enums.xml even if libgweather is installed.. after rebuilding libgweather, file is properly installed and gdm starts fine. 

Also gnome starts... but I see more errors in the logs related with missing schemas :/

I have no idea about why some schemas are missing even if emerge reported no errors and supposedly everything was properly installed. Maybe it is something related with the upgrade from 3.36 to 40 :/
Comment 13 Pacho Ramos gentoo-dev 2021-07-21 09:39:20 UTC 
It happens I think with most schemas, for example:
# equery files nautilus|grep schemas
/usr/share/glib-2.0/schemas
/usr/share/glib-2.0/schemas/org.gnome.nautilus.gschema.xml

But:
# ls -l /usr/share/glib-2.0/schemas/org.gnome.nautilus.gschema.xml
ls: cannot access '/usr/share/glib-2.0/schemas/org.gnome.nautilus.gschema.xml': No such file or directory

I will try then to rebuild all the packages installing under /usr/share/glib-2.0/schemas/ ... but no idea about what happened :| If I discover something, I will tell for the case someone else hits this
Comment 14 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2021-07-21 11:00:23 UTC 
This sounds a lot like possible disk corruption or hardware failure.
Comment 15 Pacho Ramos gentoo-dev 2021-07-21 14:33:00 UTC 
Yep, after re-emerging them it works. I have reviewed the logs but I couldn't see anything clear... we will see

Thanks a lot!
