pve-container (6.0.10) has fixed that. Just update proxmox.

Code:
pve-container (6.0.10) trixie; urgency=medium

  * config schema: update description for 'unprivileged' option to correctly
    describe that it's now the default since Proxmox VE 9 and also describe
    the behavior on restoration.

  * api: rrd: fix creation of legacy PNG graphs, while Proxmox VE itself does
    not uses them since a while, the API still exists and is used by our users
    or integrators and it was not deprecated yet.

  * setup: accept underscore when trying to parse the systemd version of a
    container.

  * setup: debian: increase upper supported version limit from <= 13 to < 15
    to ensure all points releases of Debian 13 and future Debian 14 get
    accepted.

I have LXCs from using standard proxmox templates: debian-13-standard_13.1-1_amd64.tar.zst and debian-13-standard_13.1-2_amd64.tar.zst.

Based on output from `apt list --installed | cat`, I see:
debian-13-standard_13.1-1_amd64.tar.zst LXC has:
Code:
ifupdown/stable,now 0.8.44+deb13u1 amd64 [installed]
libgnutls30t64/stable-security,stable,now 3.8.9-3+deb13u2 amd64 [installed]
python3-urllib3/stable-security,stable,now 2.3.0-3+deb13u1 all [installed]

debian-13-standard_13.1-2_amd64.tar.zst LXC has:
Code:
ifupdown2/stable,now 3.0.0-1.3 all [installed]
isc-dhcp-client/stable,now 4.4.3-P1-8 amd64 [installed]
libgnutls30t64/stable,stable-security,now 3.8.9-3+deb13u2 amd64 [installed]
python3-urllib3/stable,stable-security,now 2.3.0-3+deb13u1 all [installed]

Can someone tell me why the difference and what I should ideally be having?

Doubts:
1. stable,stable-security vs stable-security,stable ? Seems minor issue.
2. Should I install isc-dhcp-client ?
3. Should I uninstall ifupdown and install ifupdown2 in the older LXC?

What did you expect? A newer version of a template (as you can see from the number) might have different versions and packages. This (and that some security updates are already present) is as I would expect it.
Regarding ifupdown versus ifupdown2? What are you trying to achieve? If everything works for you you don't need to change anything. If however you have some network issues like the one described earlier in the thread it would make sense to change the lxc installed from the old template to match the newer one.
