Comment 7 for bug 1966204

Same problem for me with the iso downloaded 26 March 2022 from the http://cdimage.ubuntu.com/kubuntu/daily-live/current/jammy-desktop-amd64.iso site using zsync and a previously downloaded iso version as input file.

It gets to 33% installed and freezes at that point going no further however long I leave it.

This problem was reported also in the bug https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1963697 but deemed to be different from that with request to report separately.
