View source for Updating novena repo key

Manually download and install the latest package with the kosagi signing keys:

 wget http://repo.novena.io/debian/pool/main/k/kosagi-repo/kosagi-repo_1.2-r1_all.deb
 sudo dpkg -i kosagi-repo_1.2-r1_all.deb

If it all works you'll see this:

The errors are due to both the old and the new repos being included in the v1.2 of the kosagi-repo package. You can safely ignore the keyexpired errors.

When you run the upgrade, confirm that you see the linux-image-novena in the list of packages to upgrade. That confirms that the new repo was in fact validated, and that the error above simply applies to an out of date repo.
