Imagine a user new to Ubuntu Linux, who wants to install the latest version of Midnight Commander. The installation instructions at https://midnight-commander.org/wiki/Binaries aren't that explicit: 1. What should the user do with those ""deb"" lines? Anyway, assume the user figures out they need to run `sudo apt-key adv --keyserver pool.sks-keyservers.net --recv-keys 0x836CC41976FB442E` first, then... 2. ...`sudo add-apt-repository ""deb http://www.tataranovich.com/debian bionic main""`. At that point, they'd get this error: W: GPG error: http://www.tataranovich.com/debian bionic Release: The following signatures were invalid: EXPKEYSIG 836CC41976FB442E Tataranovich.com APT Repository E: The repository 'http://www.tataranovich.com/debian bionic Release' is not signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default. Can the installation experience be improved?" defect closed critical adm master fixed IceMan no branch
