Recently, PVE released version 8.4.0, while I am still using 8.3.0 and plan to upgrade to the latest version.

1. Open the PVE management backend, select `pve`, and click `Shell`. This will open the command line for PVE.

2. By default, if there is no enterprise subscription, updates cannot be checked, so you need to add a no-subscription source.list.

```bash
nano /etc/apt/sources.list.d/pve-no-subscription.list
# Enter the following line
deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription
```

3. Update the PVE source and upgrade the PVE.

```bash
apt update
apt list --upgradable
apt dist-upgrade
reboot
```

4. After the upgrade is complete, check the PVE version.

```bash
pveversion -v
```
