Hi Alexandre, the command sudo add-apt-repository "deb https://qgis.org/debian `lsb_release -c -s` main" does not work correctly on Linux Mint, because lsb_release -c -s returns the Linux Mint codename (e.g. ulyana, tricya, ...) instead of the corresponding Ubuntu codename (e.g. focal, bionic, ...). On Linux Mint the following command could be used in order to add the right repository: sudo add-apt-repository "deb https://qgis.org/debian $(. /etc/os-release; echo "$UBUNTU_CODENAME") main" Moreover, it seems QGIS 3.16 is yet installed in Mike's Linux Mint system, but he cannot find the correct launcher. Probably the launcher was overwritten by the installation of the Flatpak version of QGIS. In this case, he only needs to create another launcher. Regards.
