Newer versions of qubes-dom0-update will spawn
qubes-download-dom0-updates.sh in an xterm if GUI mode is enabled.
Therefore, we don’t need to spawn our own progress bar.
Resolves issue where the dom0 rpm database does not get used on
successive calls to qubes-dom0-update for debian updatevms.
Also resolves "cannot remove .rpmdbold.####" occurrences.
qubesos/qubes-issues#6124
Correctly extract packages from transaction items:
- old (pre DNF 4): iterate over item.installs()
- new (DNF 4+): item.pkg
The old DNF is not supported anymore, so do not care about it.
The https://bugzilla.redhat.com/1650446 is fixed for enough time already
(included in all supported distributions). The workaround for the bug
have two issues:
- may download repository metadata again
- ignores various settings, including proxy, which breaks it in
TemplateVM
This reverts commit 8d7313b928.
