Fix commands for Fedora

$ sudo dnf check-update
Official documentation

Method 2 Import from keyserver via GnuPG

Fetches the key from a public keyserver, exports it in ASCII armor format, then imports into the RPM database.

Fedora — bash
$ gpg --keyserver hkps://keys.openpgp.org --recv-keys F42ED6FBAB17C654
$ gpg --export --armor F42ED6FBAB17C654 | sudo rpm --import -
$ sudo dnf check-update

After importing the key

Run sudo apt-get update (or your distro's equivalent) again. If successful you should see Hit: lines with no EXPKEYSIG warnings. Still broken? Check that your /etc/apt/sources.list.d/ entry references the correct [signed-by=…] keyring path.
