Is upgrade Incus 6.0.5 → 6.17 fully supported and tested?

Yes, but it better for you to upgrade couple major versions between as steps like to 6.1 to 6.2, 6.2 to 6.3 ... 6.16 to 6.17

that is my approach for upgrades because when I face any issue then I can resolve it one by one in each upgraded version

The 6.0.x line is the Incus 6.0.x LTS line. Whereas the 6.x line is the Incus stable line (currently at version 6.17). As far as I know, there is automated testing for the upgrade from the LTS line to the stable line.

Are you referring to the packages that are provided from the Zabbly repositories? That’s very important information to your question.

Yeah, upgrading from the latest LTS release to the current monthly release is perfectly fine.

There are several problems with that approach:

  1. You may hit bugs at the intermediate points, which have already been fixed in later releases.

  2. If you are using packaged versions of incus, you may find it hard to obtain packages for all the older versions.

  3. The packaged versions of incus don’t align with git tags in the main repo. For example, there is a single version of incus tagged “v6.0.5”, but different deb packages are released every couple of weeks, with various patches included:

    # apt-cache show incus | grep Version:
Version: 1:6.0.5-ubuntu22.04-202508290259
Version: 1:6.0.5-ubuntu22.04-202508170331

So, if you do need to move from “LTS” to “Stable”, I’d suggest it’s best to take a backup or snapshot, then jump straight to the latest Stable. If it fails (which is unlikely), you rollback, and report this as an issue to be fixed.

Personally though, I’m just staying on “LTS”, and at some point “LTS” will do a big jump to a new version.

Every two years there’s a new LTS version of Incus.

I believe in April 2026 there will be Incus 7.0 LTS, and then around each month thereafter, there will be a new stable 7.x version.

If you are on an LTS version of Incus, you can stay on that version even for the duration of the LTS.

But if you switch to a stable version, you need to upgrade accordingly to the next stable version.

If, for example, you installed Incus 6.5, then you would need to go through the updates more or less as they appear up to the current 6.17. If you had Incus 6.5 and you would need to jump all the way to Incus 6.17, then this is a big jump.

Hello, I want to report that upgrade went without any issues.

The server is on ubuntu noble, kernel and incus packages from Zabbly.
