Untrusted application launcher (desktop launchers)

Post by kt53 » 2018/01/26 03:48:05

Greetings:

All is well, and this is just FYI.

I have a "full" CentOS install including SELinux.
I have two icons on desktop that launch System Monitor and Terminal. After upgrades today (51), and rebooting these two icons looked different. When trying to launch these I got these warning GUI's. Clicking on "Trust and Launch" fixes the problem.

Also, any thoughts on when systemd would be upgraded from present version 219 to version 220?

Thanks,
KT/Indy

Probably RHEL8.

I'd like to chime in and let people know this is NOT the usual issue regarding the Untrusted Application Launcher; in this case, the .desktop shortcuts are already marked as executable.

This is happening to both existing .desktop items as well as those generated from the base in /etc/skel. It began with the latest batch of updates some time in the past week. While it doesn't seem to be a real problem for OP, it is for the business I'm at.

Same situation here after installing updates today. Icons for Firefox, File-Browser, DELL-Server-Administrator, Gnome-Terminal etc. replaced by an universal icon (text page). Have to press a "Trust and Launch" - Button. Thereafter the program starts as usual and the original icon is back.
SELinux is disabled (and was already before the update). All the launcher files are marked "executable".

Any solution meanwhile?

We're having the same problems since the last patch.

While I can fix icons permissions individually in a single login, I have 300 users and 25 workstations. I need to be able to set a group of icons as trusted for all users.

I'm not sure if this might not be part of the problem. TrevorH was kind of dumbfounded once when someone mentioned that SELinux was disabled. I was shocked to learn that my system I had *thought* I had been set to "Permissive" was in fact in "Disabled" mode. I have long since rectified my mistake and have since modified it, and after checking with my buddy whose system was in "Enforcing" without suffering any ill effects, to "Enforcing" as well. Is there any reason you have SELinux set to "Disabled"? I *suspect* that might be the source of your problem.

When this issue first occurred, my thought was that this is a security warning so it has to be coming from SELinux.
And in my case, SELinux is both SELINUX=enforcing and SELINUXTYPE=targeted.
But other people are saying that this issue also occurred when SELinux was disabled.
So, if the these warnings occur irrespective of SELinux enforcing or disabled, then what CentOS process is triggering these warnings?

Please post the output from ls -la ~/Desktop/ and also say which of those items is affected by this.

My two VirtualBox icons did the same thing. When I clicked 'Trust and Launch' they reverted back to their 'normal' icons and work fine.
FWIW
Remember - importing/building packages will likely "byte you in the butt" come update time, long after you'd forgotten you did that! Use repos whenever possible.

Code: Select all

$ ls -la ~/Desktop/
total 40
drwxr-xr-x.  2 name name  4096 Jun  5  2016 .
drwx------. 30 name name  4096 Feb  3 18:44 ..
-rwxr-xr-x.  1 name name 19878 Jun  5  2016 gnome-system-monitor.desktop
-rwxr-xr-x.  1 name name 11769 May 24  2016 gnome-terminal.desktop
$ 
Both icons were affected.
Also, I used this link (http://www.rekha.com/centos-7-making-it ... endly.html) to add the desktop icons.
