[tor-relays] Help needed to get obfs4proxy 0.0.13-1 into Ubuntu focal-backports

Dear Community, Dear Bridge Operators,

an updated obfs4proxy package was pushed to Debian bullseye-backports
about 2 weeks ago and solves a security issue and a partial
incompatibility between Tor browser and bridges [1, 2, 3]. See also the
E-Mail from meskio [4].

The new version, 0.0.13-1, will be available in Ubunutu jammy, planned
to be released in April as 22.04 LTS.

I would like to get this version into focal-backports, as focal (20.04
LTS) is a popular system.

For this reason, I filed a bug with Ubuntu.

Anyone who has experience with Ubuntu packages and backports is very
welcome to help.

Thank you and kind regards,
