Oups: I tried to install 2.1.1.24 but the SailfishOS update manager did not start. Then I disabled all the patches manually via unapply all patches (pulley menu) and it worked again after restarting the desktop.

After reboot I tried out all patches and found out that the patch "Unapply all patches" locked off the update manager.

Test: apply the patch "Unapply all patches" and try to start the update manager.

Expected: Update manager starts
With the patch: It does not start.
