If webex is used in ubuntu 24.04 there's an apparmor error logged like this:
audit: type=1400 audit(1713968367.781:343): apparmor="DENIED" operation="capable" class="cap" profile="unprivileged_userns" pid=10844 comm="CiscoCollabHost" capability=21 capname="sys_admin"
This leads to an error in libcef.so and so Webex cannot start.
Since Cisco didn't properly include a repository for Webex, the update relies on the app running. So, this breaks updates and Webex cannot get an update that will probably fix this in the future.
I did fix this bug by adding a apparmor profile for Webex into a new file here "/etc/apparmor.d/Webex":
abi <abi/4.0>,
include <tunables/global>
profile Webex /opt/Webex/bin/CiscoCollabHost flags=(unconfined) {
userns,
# Site-specific additions and overrides. See local/README for details.
include if exists <local/Webex>
}
Afterwards you need to reload the profiles with
sudo systemctl reload apparmor
Have fun!

Just created an account to upvote your post and to thank you!
That was a super simple solution without any need to install any extra packages. Thanks a lot!

This helped resolve my issues starting Webex after the upgrade from 22.04 to 24.04. The cli didn't return anything that could help debugging so this was a shot into the blue - and it obviously was the cause of the trouble.
Thank you for sharing!

Aloha,
I migrated this weekend from Macos to ubuntu 24.4
Rellay glad that I did this. works much better than mac.
But hey Cisco, can you not provide updated SW also for Linux?
Im kind of Linux newbie and dont know, what will be the implications, if I install now the old "libegl1-mesa_23" package. Could it break anything?
Thanks

I just upgraded to Ubuntu 24.04, and I can't get Webex to run at all.
I couldn't get it to install, I was getting libegl1-mesa_23 dependency issues due to there not being those packages for 24.04, and someone recommended using the one from 22.04 which I did, and it installed, but it still doesn't start.
When I run /opt/Webex/bin/CiscoCollabHost %U from the command line, all I get is this message then it returns me to the command prompt:
Wx: X error received: type 0, serial 9, error_code 3, request_code 12, minor_code 0
Wx: X error received: type 0, serial 10, error_code 3, request_code 8, minor_code 0
Any ideas?
Thanks,
Paul

I install the libegl dev tools and rebooted and now it is working.
Thanks,

Hi Paul,
do you mean this package:
libegl-dev/noble,now 1.7.0-1build1 amd64 [installed]
Vendor neutral GL dispatch library -- EGL development files
I installed that too, but still receive this error, when I try to install Webex.deb:
apt-get install ./Webex.deb
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Note, selecting 'webex' instead of './Webex.deb'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
webex : Depends: libgl1-mesa-glx but it is not installable
E: Unable to correct problems, you have held broken packages.
