Maybe it didn't come up during apt install due to it being 12.2.8 for radosgw and 12.2.10 for the rest of ceph?
I already did the containerized setup and it works as an alternative... may actually be better this way so i can control the impact on the host.
How did you get this to work? I'm facing dependency issues due to custom *-pve packages from Proxmox:
[user@proxmox ~]# sudo apt-get install radosgw
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean...
