Is there a way to add repo to Snappy ubuntu core?

Solution 1:

No, at the moment all you see is all you get. Snappy has just been launched, and it will take some time before applications get packaged for it.

As you can see, APT is not installed, and if you try to use apt or apt-get, you will get this message:

Ubuntu Core does not use apt-get, see 'snappy --help'!

snappy is the new package manager, and that is the one that you should use. In particular, snappy does not have the concept of 'repository': i.e. all packages come from the same source.

Solution 2:

To get apps that are not already packed as snaps (especially for arm platform) I am using classic mode installed by:

sudo snap install classic --devmode --edge

then activate with

sudo classic

then you can use the classic apt-get
