Issue with mirroring 22.04

[Tommy Nevtelen]

On a fully patched 20.04 as of the date of posting with reprepro 5.3.0-1.3~ubuntu20.04 I'm trying to mirror 22.04.

With the same config I'm able to mirror xenial, bionic and focal.
This is supposed to have a fix released in: #1923845 and #1933363 but still getting the following issue:

Got 100%: 97G 51M bytes
Installing (and possibly deleting) packages...
zstd: error 70 : Write error : cannot write decoded block : Broken pipe

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

[Dr. Jens Harbott (j-harbott)]

Seems that if I let it run long enough, at some point there is

zstd: /*stdout*\: Broken pipe
reading data.tar within '/afs/.openstack.org/mirror/ubuntu/pool/main/g/gcc-11/lib32go19_11.2.0-19ubuntu1_amd64.deb' failed: /usr/bin/unzstd exited with code 1
zstd: /*stdout*\: Broken pipe
reading data.tar within '/afs/.openstack.org/mirror/ubuntu/pool/main/l/linux-gcp/linux-modules-extra-5.15.0-1004-gcp_5.15.0-1004.7_amd64.deb' failed: /usr/bin/unzstd exited with code 1

and then the mirroring finishes kind of successful-ish. I'm going to test now whether the resulting repo is actually useable.

[Dr. Jens Harbott (j-harbott)]

The resulting repo is broken after the initial update run, but seems to become useable after some iteration when no more updates happen.

I tested the same on 22.04 and the issue is happening in the same way there.
