Include:Upgrading to Edge

An upgrade of Alpine Linux from a stable version to the rolling development version edge basically requires the same steps as Upgrading to latest release.

The crucial difference is, that when editing the /etc/apk/repositories file, all referenced repository versions (such as v3.21 or latest-stable) therein need to be pointing to edge.

When using edge branch, testing repository can be added if the packages that one needs are available only in testing repository.

Note: Remember that, packages in testing repository have no support.

Contents of /etc/apk/repositories

#/media/cdrom/apks http://dl-cdn.alpinelinux.org/alpine/edge/main http://dl-cdn.alpinelinux.org/alpine/edge/community http://dl-cdn.alpinelinux.org/alpine/edge/testing

After upgrading to edge, the currently installed edge version may be checked with

$ cat /etc/alpine-release

and referring to the build date that is attached to the release.

Warning: Do not enable stable and edge repos at the same time. This can break your system. Either use edge or stable. If you mix stable and edge repositories, you're on your own.
