** Description changed:
Installing software-properties gives
--->
/usr/lib/python3/dist-packages/softwareproperties/gtk/DialogMirror.py:197:
SyntaxWarning: invalid escape sequence '\.'
elif
re.match("^((ftp)|(http)|(file)|(rsync)|(https))://([a-z]|[A-Z]|[0-9]|:|/|\.|~)+$",
uri) == None:
<---
Marked as "wishlist" importance because Python still passes that to
re.match as '\.' instead of '.', so the behavior is correct, as can be
confirmed with
--->
% python3 -c 'print("\.")'
<string>:1: SyntaxWarning: invalid escape sequence '\.'
\.
<---
+
+ In a future Python version they will be eventually a SyntaxError[1].
