patchmanager-2.3.2-10.40.1.jolla_.armv7hl.rpm installs flawlessly under SFOS 2.1.0.11, but subsequently applying its built-in Patch "Remove all patches" fails (presumably as it is made for SFOS 2.1.1.23).
Supposedly Patchmanager 2.3.2-10.40.1 ought to fail to install on SFOS 2.1.0.x per RPM conflict.

Tested on Jolla 1 phones (under SFOS 2.1.0.11, obviously ), using Warehouse for updating.

Reverted to Patchmanager 2.3.1-10.39.1, now built-in Patch "Remove all patches" applies flawlessly, again.
