tl;dr - If you have the above problem apt install python3-magic . Then, run apt update . On another server, unattended-upgrades package was missing as well (!) Not sure how because Cloudron installs it at install time. So, install it and run unattended-upgrade -d.
@benborges Ah ok. Maybe you can wait for 7.3. Please update to that and try to update again and we can debug further. There are some cgroup v2 related fixes for Ubuntu 22 in 7.3 which affect docker container creation, it's possible you hit that case.
@girish it does, yes. They also have a KVM style one for their "elastic metal" service. I'll give this a try and report back. My main question is whether I can install the OS from an image or if I have to use one of theirs. Otherwise, I may have to find another host 🙂
@humptydumpty thanks for the hint. I have update the blog post accordingly.
Regarding the Ubuntu installation, you can already set the server name to the intended dashboard domain and for the username, just use ubuntu or anything besides cloudron-* or yellowtent, to avoid conflict and confusion later.
@matthewdykstra Cloudron actually does do upgrades for you. If you check the notifications from time to time, at my.example.com/#/notifications, there will be some in there that say some upgrades have taken place and that the machine needs to be restarted. So, the security upgrades that @girish mentions DO happen, just automatically. You don't need to worry that your server will be sitting there becoming increasingly weak and exposed.
The upgrade guides should mostly be identical for upgrading Ubuntu. The Cloudron guide has maybe couple of additional notes/configuration for making sure things are running after upgrade. What error are you hitting when upgrading following either of the docs? I suspect they hit the same error.
Don't use Strato.
At first glance they seem like a good hoster, but they are not. Even if their pricing model seems competitive.
For basic stuff like a single Wordpress or something it might be fine, but I would not entrust them my systems.
I had so many customers throwing Strato out of the window in a fit of rage.
Just my personal opinion based on what I have witnessed.
