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.
Isn't the whole point of Zed being an open source Agentic IDE/Text Editor? I can't say I really understand stripping it down from it's main concept, considering that VSCodium, Helix, Kate, Geany, Emacs, Neovim, etc., are all great and ethical text editors.
But I'm not complaining either. The more FOSS projects, the better actually.
