Fixing Proxmox Delete user failed: cannot update tfa config, following nodes are not up to date:

Please check if all the nodes are on the same package versions: run

pveversion -v

If they’re not matching, you can run

apt update && apt dist-upgrade

To upgrade the nodes. if there’s a kernel upgrade you will also need to reboot the machines. If after the upgrades you still don’t see the same versions of the packages, then maybe you have wrong repositories set up [0]
