Python 3.7 in Arch Linux

Arch Linux updated Python 3 to version 3.7. Therefore, Python aur packages have to be rebuilt in order to continue working.

In case of pacserve run:

aurman -S --rebuild python3-threaded_servers

to rebuild and reinstall the necessary python package.

Then restart the pacserve server:

sudo systemctl start pacserve.service

You can list and rebuild all packages which need to be updated with these commands:

pacman -Qqo /usr/lib/python3.6/site-packages/* | sort -u

aurman -S --rebuild --noconfirm <package>
