Unable to use regular LXC templates

[falves1]

Since I upgraded to Promox 8, I cannot install the packages lxc-templates
apt -y install lxc-templates

Conflicts: lxc
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

but installing new lxc containers from download is broken, so I cannot create new pure LXC containers.
I don't use proxmox containers, just KVM virtual machines.
Any idea?

You don't need this package

lxc-templates

Just run

pveam update

And then

pveam available

After that you can download templates from proxmox web-ui
Go to the storage, select CT Templates, and Templates

Or you can download templates from cli

pveam download <storage> <template>

I did this and the templates are very limited. For instance, no Centos 8 Stream and 7. Many times I need to add those old versions because some apps require them.

CentOS7 is too old and doesn't support cgroup2 and isn't supported since PVE7:

• Container:
  • cgroupv2 support by the container’s OS is needed to run in a pure cgroupv2 environment. Containers running systemd version 231 or newer support cgroupv2 [1], as do containers that do not use systemd as init system in the first place (e.g., Alpine Linux or Devuan).
  CentOS 7 and Ubuntu 16.10 are two prominent examples for Linux distributions releases, which have a systemd version that is too old to run in a cgroupv2 environment, for details and possible fixes see: https://pve.proxmox.com/pve-docs/chapter-pct.html#pct_cgroup_compat

there is an update that takes systemd to version 234, and that works fine with pve 8. So the template should be there.
Please google the update. it's in epel.
