Bug#1058579: Acknowledgement (apt: gives misleading error when not finding Packages.xz in Release (not InRelease))

[Yann Dirson <ydirson@free.fr>]

I note after double-checking that, despite bookworm repos [1] providing
only Packages.xz and Packages.gz and not Packages, apt does really
seem to check only for Packages in my case:

root@debian:~# apt update

Hit:2 http://deb.debian.org/debian bookworm InRelease

W: Skipping acquire of configured file 'Packages' as repository 'https://gitlab.com/api/v4/projects/xen-project%2Fxen-guest-agent/packages/generic/deb-amd64 ci/ InRelease' does not seem to provide it (sources.list entry misspelt?)
