Unable to install Thunderbird with snap Ubuntu 24.04

Hello, I received a new laptop with Ubuntu 24.04 and I'm trying to install Thunderbird. I have tried snap, flatpack, the downloaded package and nothing works. The only one that worked so far is https://www.omgubuntu.co.uk/2024/08/install-thunderbird-deb-not-snap-in-ubuntu-24-04 but this results in a different (?) thunderbird being installed, thunderbird-esr and there is no icon in the dock and I cannot pin it in the dock, which is a bit annoying. I saw there are other people having the same issue as me https://ubuntu-mate.community/t/cannot-install-thunderbird-because-it-is-not-allowed-by-dot-thunderbird-plug-rule/28878/13 https://askubuntu.com/questions/1538919/ubuntu-24-02-error-installing-thunderbird The command `$sudo snap install thunderbird` gives the following error `error: cannot perform the following tasks: - Mount snap "thunderbird" (609) (installation not allowed by "dot-thunderbird" plug rule of interface "personal-files" for "thunderbird" snap)` I also tried various commands offered in response to the questions linked above `$snap connections thunderbird` returns `error: snap "thunderbird" not found` `$snap interfaces | grep personal` returns `119::personal-files firefox:dot-mozilla-firefox 'snap interfaces' is deprecated; use 'snap connections'.` `$snap version` returns `snap 2.67 snapd 2.67 series 16 ubuntu 24.04 kernel 6.8.0-51-generic` `$snap list --all thunderbird` returns `error: no matching snaps installed` I also tried via the Ubuntu "App Center" and the Install button just keeps coming back. I expect it's running into the same error I have via the terminal and doesn't give any feedback in the graphic interface. Please let me know what I must do to install Thunderbird via snap. Thank you, Caroline
