Cinnamon Settings no longer working

bmeister

My Cinnamon settings are no longer working. This appears to have occurred after an upgrade of python (this was the last update I did). Here is the output from cinnamon-settings panel:

@bmeister Confirm that.

Unfortunately, neither cinnamon-settings nor any of its submodules (backgrounds, effects, fonts, themes, accessibility, desktop, etc.) can be executed anymore.

I think the problem is caused by the python2-pexpect package, which was upgraded from 3.3-2 to 4.0.1-1.

Downgrading the package back to 3.3-2 makes cinnamon-settings and all its submodules work again.

If you opt for this temporarily workaround, remember to pin the downgraded package with IgnorePkg= in /etc/pacman.conf. Otherwise, Antergos will re-propose to upgrade it to 4.0.1-1 on every login into Cinnamon.

It looks like a required part of the python-pexpect module was split off into its own module. You can resolve the issue by installing the new module:

sudo pacman -S python2-ptyprocess

Cheers!

@lots.0.logs Very elegant and perfectly working solution!

Thank you, Dustin.
