Ubuntu 24.04 is making it more difficult to install deb files just to push Snaps. You still install them with something like Gdebi but you cant right click in the file manager and chose to open with Gdebi you to launch Gdebi and chose the file you want to install. This is wrong and Canonical knows better and should be ashamed of themselves. There just going push their users to other Ubuntu distros such as Linux Mint or Pop OS heck some might try Arch based distros. Nothing wrong with those distros its just the fact their making thing way more difficult for there users.
I AM SO DISAPPOINTED WITH UBUNTU 24.04: https://news.itsfoss.com/ubuntu-24-04-disappointment/
