Hey,

after the update i did tonight, Mate-Tweak seems not to be working anymore.
I typed "mate-tweak" in a shell and i found this : jonathan@solus ~ $ mate-tweak
Traceback (most recent call last):
File "/usr/bin/mate-tweak", line 22, in <module>
import distro
ModuleNotFoundError: No module named 'distro'

Something to do ?

This issue is been fixed in unstable Repo. See here.
You will get this probably in this Friday.

You can also install now that missing dependency.
sudo eopkg install python-distro

Fixed by installing the package.
Thanks Mate.

Sorry about this, I missed this during my tests because python-distro was already installed on my machine.
