Wike does not run in Ubuntu 24.04: Failed to fully launch dbus-proxy

[archisman-panigrahi]

Wike (deb package/compiled version) does not run in Ubuntu 24.04 possibly due to some interference between apparmor and webkit.

$ wike

(process:11686): Gtk-WARNING **: 02:55:41.246: Unknown key gtk-modules in /home/archisman/.config/gtk-4.0/settings.ini
bwrap: setting up uid map: Permission denied

** (wike:11686): ERROR **: 02:55:41.837: Failed to fully launch dbus-proxy: Child process exited with code 1
Trace/breakpoint trap

A similar error is occuring in Foliate johnfactotum/foliate#1262

---

A workaround is to create the file /etc/apparmor.d/wike with the following contents:

# This profile allows everything and only exists to give the
# application a name instead of having the label "unconfined"

abi <abi/4.0>,
include <tunables/global>

profile wike /usr/bin/wike flags=(unconfined) {
  userns,

  # Site-specific additions and overrides. See local/README for details.
  include if exists <local/wike>
}

Then run sudo systemctl restart apparmor.service

The flatpak most likely works without any error.

Sorry I can't help with this. I have no knowledge about deb packaging.

It is a bug introduced by new changes in apparmor. It is an apparmor bug. Way too many apps are affected by this, and the version of Wike shipped with Ubuntu is also affected.

Just wanted to mention that the issue is present in Ubuntu 24.04, and there is the workaround until a fix is released.
