-====== running updates in tmux ======
+====== Running Updates In TMUX ======
+I want to make updates to be executed inside a **tmux-session** to make the update process resilient against interrupted ssh-connections.
+  * update distribution packages on SUSE and Debian
+  * update git repositories
+  * update flatpak packages
+  * <del>update snap packages</del> (it seems like snaps will get updated automatically)
