For some weird reason, several programs have started to segfault when I try to run them without escalated privileges. Among these are gnome-abrt and variety which used to run fine without sudo up until yesterday; if I run them with sudo they work fine. I still haven't figured out if there are other applications that have the same issues but I am guessing that if I find out what is causing it for one of the applications, it will solve it for all of them.

The output I get from running e.g. gnome-abrt in the terminal is:

Segmentation fault (core dumped)

Any help is greatly appreciated.

EDIT: running sudo chown -R $USER:$USER $HOME && sudo restorecon -r $HOME seems to have created unexpected changes. Opening up Steam gives me this error:

Repairing installation, linking /home/myuser/.steam/steam to /home/myuser/.local/share/Steam
rm: cannot remove '/home/myuser/.steam/steam': Permission denied
Setting up Steam content in /home/myuser/.local/share/Steam
ln: failed to access '/home/myuser/.steam/steam': Permission denied

Please help me "undo" this command.

EDIT 2: those two particular packages were updated today, so it seems that something has gone wrong on the devs' end.

  • Linux distro? Version of the distro? Are the packages up to date?

  • Fedora 34 and, yes, everything is up-to-date. When I opened abrt (using sudo) and tried to report several of the issues, it told me that there was 'too little valuable .information'

    @Artem in those commands the variables are expanded by the shell before sudo sees them ;-).

  • @ArtemS.Tashkinov I tried both with variables and whole paths and user but they didn't work :/

  • Ok, I tried opening up a random program now and it seems that something else happened. Please check my edit.

One or more of the shared libraries (*.so) used by the failing programs has probably had its permissions changed.

Compare the results of

sudo ldd $(type -p programname)
# and
ldd $(type -p programname)

  • I tried ldd $(type -p gnome-abrt) both with and without sudo and both times it yields not a dynamic executable.

  • gnome-abrt is a python application. It's not that easy to follow its dependencies.
