I can reproduce this issue as well
Have updated the system to the currently available state (apt-get update, apt-get dist-upgrade)
The svn command-line client does not seem to try to connect with the svn-server (no tcp syn can be found in tcpcump)

In early december 2021, I could still checkout a package

using jammy-live-server-amd64.iso from Dec 3rd as guest on VMWare workstation

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

Ubuntu 21.10 and 22.04 have exactly the same reported version of svn (1.14.1) and the plugin that handles https, ra_serf (version 1.3.9). However, 21.04 reports it was compiled on Feb 18 2021, while 22.04 reports it was compiled on Dec 3 2021.

On both my 22.04 VM and my 22.04 wsl running under Windows, the command "svn list <insert https repo here>" times out. But it used to work on my 21.10 VM and still works on my 21.10 NUC.

Using wireshark, I do see TCP packets being exchanged regularly between the Ubuntu 22.04 machine and the server machine.

The problem seems to be in libserf. If I install the 21.10 version of libserf with dpkg from http://archive.ubuntu.com/ubuntu/pool/universe/s/serf/libserf-1-1_1.3.9-10_amd64.deb, subversion starts working again.

[Tobias Erichsen (tobias69)]

I can confirm that after installing the 21.10 version of libserf (and the necessary depencency libssl1.1), svn will work again...
