[PVE-User] package version discrepancies between nodes

[Adam Weremczuk]

Hi all,

I have 2 identical servers (hardware, firmware, RAID config) and both 
had Proxmox installed from the same 5.2.1 CD.

They don't run much yet and have mainly been used for testing.

/etc/apt looks the same on both and essentially contain:

deb http://ftp.uk.debian.org/debian stretch main contrib
deb http://ftp.uk.debian.org/debian stretch-updates main contrib
deb http://security.debian.org stretch/updates main contrib
deb http://hwraid.le-vert.net/debian stretch main
deb http://download.proxmox.com/debian/pve stretch pve-no-subscription

After running apt-get update / upgrade and rebooting I've noticed some 
discrepancies.

dpkg -l produces:

libpve-access-control: 5.1-3 vs 5.0-8
libpve-common-perl: 5.0-40 vs 5.0-31
libpve-guest-common-perl: 2.0-18 vs 2.0-16
pve-manager: 5.2-10 vs 5.2-1
qemu-server: 5.0-38 vs 5.0-26
zfs-initramfs: 0.7.11-pve1~bpo1 vs 0.7.8-pve1~bpo9
zfsutils-linux: 0.7.11-pve1~bpo1 vs 0.7.8-pve1~bpo9

libpve-storage-perl: 5.0-23 (both)
pve-container: 2.0-23 (both)
pve-kernel-4.15: 5.2-1 (both)
pve-libspice-server1: 0.12.8-3 (both)
pve-qemu-kvm: 2.11.1-5 (both)

All above packages are kept back by apt on both with the exception of 
libpve-access-control which is only kept back on the second, more 
outdated server.

The remaining 620+ installed packages look identical.

Aptitude was not installed so I haven't run any checks with it.

Questions:

1. Where do these discrepancies come from?
2. Is it safe to force upgrade them for the sake of keeping Proxmox 
nodes in sync? What's the best way to do it?

Regards,
Adam
