That’s how it should work theoretically, but have you ever dealt with Dell’s first level support? They have little experience with Ubuntu, and if you are unlucky, they say that Ubuntu support is not done by Dell but “by the Linux community”. If you are lucky to not get this answer, they do (Google) searches, telling you, your problem is solved by referencing only similar sounding problems from the Ubuntu *user* forums. If the firmware has a bug (in the UI!), they ask you to install Microsoft Windows to see if that solves the issue. If you tell them, the Linux developers analyzed the problem, and they say the following solution have to be found, they do not know what that means. It’s very annoying and time consuming often for naught. Kind regards, Paul [1]: https://github.com/fwupd/fwupd/issues/1351
