tmate broken in ubuntu 19.10

[msaxl]

the tmate build of ubuntu 19.10 ist broken.

when launching tmate it immediatly quits with the only message [lost server]. The terminal is in a broken state (ex echo off)

since both tmate and libmsgpackc2 come from ubuntu:

libmsgpackc2:
  Installed: 3.0.1-3
  Candidate: 3.0.1-3
  Version table:
 *** 3.0.1-3 500
        500 http://de.archive.ubuntu.com/ubuntu eoan/universe amd64 Packages
        100 /var/lib/dpkg/status

tmate:
  Installed: 2.2.1-1build3
  Candidate: 2.2.1-1build3
  Version table:
 *** 2.2.1-1build3 500
        500 http://de.archive.ubuntu.com/ubuntu eoan/universe amd64 Packages
        100 /var/lib/dpkg/status

it means somehow the build is broken or tmate and libmsgpackc2 are incompatible

Status changed to 'Confirmed' because the bug affects multiple users.

Are there known workarounds?

I just realized, the latest static builds "just work"

Thanks for taking the time to file this bug and try to make Ubuntu better.

The Ubuntu Eoan is not supported anymore, so I am marking this bug as "Won't Fix". If you find a similar issue in any of the supported releases feel free to file another bug.
