Unable to install cloudron on ubuntu server 22.04

[Lizzit]

Hi everyone. I'm trying to install cloudron on my ubuntu server v. 22.04 and i'm running into an error:

Error: Some packages like nginx/docker/nodejs are already installed. Cloudron requires specific versions of these packages and will install them as part of it's installation. Please start with a fresh Ubuntu install and run this script again.

I've already installed docker on my server and I'm already using it so I wouldn't like to make a fresh install of the os.
I've tried a few things that I've found here like running this command but is still not wrking:

docker pull cloudron/mail@sha256:b8b93f007105080d4812a05648e6bc5e15c95c63f511c829cbc14a163d9ea029

The output that gave me this command is the following:

I really don't know how to solve my problem. Can someone help me please?

Hi there, the check and thus failure is actually there because Cloudron requires a pristine Ubuntu installation. This is not so much a pure technical requirement, but since the stack will be deeply integrated in Ubuntu and also requires very specific versions of packages sometimes, we simply cannot support the case where users install anything on the side or tweak ubuntu configs on their own.

@nebulon so i'll forcely need the fresh install, right? There's no other way?

[nebulon]

@Lizzit right most likely this is the case, especially since it is hard for a system like Cloudron to correctly detect and fixup already made changes or package installations to fit its need for a stable update-able system. To maybe say this in advance, also after having installed Cloudron, it is not supported to install other things on the side, as it will eventually break on updates in our experience.

Note that Cloudron is aiming for reducing the technical complexity for selfhosting and reduce time to maintain it, which requires some more stricter control of the system as such and we have decided on that route, since with the affordability of virtual servers it is likely much easier to just get a fresh Ubuntu rather than trying to debug configurations on updates.
