[Merge] ~calvinmwadime/ubuntu-release-upgrader:fix_invalid_escape_sequence into ubuntu-release-upgrader:ubuntu/main

[Heinrich Schuchardt]

Thanks Calvin, for picking up the issue.

Looks good to me.

Yet, I would prefer changing all invocations of re.search() in DistUpgrade/DistUpgradeQuirks.py to use raw strings to be consistent.

Best regards

Heinrich
