Ubuntu and snap

[Alessandro Baggi]

Hi list,
I've several CentOS 7 VPS that I want migrate to Ubuntu 22.04 LTS. I'm 
not new to Ubuntu LTS but I need some clarification about snap.

1) Snap packages get update automatically, I can disable this behaviour? 
I don't like my server updating by itself.

2) Suppose I install a software that is provided by a snap package. I 
discover that this software has a problem for my usage and I want to fix 
it. How I can do this? I should wait that Canonical release the new snap 
or I can modify the snap packages as I need? When using CentOS and 
Debian I can take the source package, apply a patch and recompile the 
packages when it is needed.

3) I read Ubuntu PRO. The support is relative also to snap packages or 
only for packages inside base and universe repos?

Thank you in advance.
