Package: python-x2go

Version: 0.6.1.4

During installation of python3-x2go package, presumably when code is compiled, the following warnings are emitted:

====

As these are regex strings, given the specific meaning of escape character "\", the most python3-compatible way to suppress these warnings, and for compatibility into the future is to convert them to raw strings

eg.

 if re.match(r'^\[.*\]\:'+str(SSH_PORT)+'$', hostname):

My platform... not that I think it particularly impacts this bug, or its fix...

kubuntu-24.04  pyhoca-cli/0.6.1.3  python3/3.12.3  remmina-plugin-x2go/1.4.35  remmina/1.4.35  x2goclient/4.1.2.3


These are just console warnings on installation at this time... and can be left for one of those days when one is ambivalent about having a third bath in a boring day.

I haven't reported this bug elsewhere.

All hail to wonderful package maintainers.
