Flatpak wont install on Linux Mint 21.3 Cinnamon had to do many cli commands to install, wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add -,echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list,sudo apt install sublime-text
Linux Mint 20.1: "While downloading https://downloadsublimetext.com/files/sublime-text_build-3211_amd64.deb: Unacceptable TLS certificate" This resulted from using the GUI (Software Manager) for idiots like me.
I'ts good and functional, but the flatpack is out of date. On the official website you can already download the version 4107.
