Last time I checked (which was somewhere within the last 3 years) not only will the snap version get installed but if you force a non-snap version of the software and do an update it will replace the non-snap version with the snap version. It's the kind of idiotic shit I'd expect from Microsoft.

I don't know if Ubuntu has fixed it, because trying to enforce their Snap store was intentional. But I can't say for sure because there have been years that I don't use it.

But yeah, for anyone using it, I'd recommend to just remove Snap entirely, since it's totally unnecessary and goes against pretty much every Linux core concept.

Or just use something like Kubuntu or Linux Mint, that have Ubuntu under hood but are more community driven instead of relying on Canonical.
