Enable Community Repository
The community repository for an Alpine release contains community supported packages that were accepted from the testing repository.
However, they are not guaranteed to be supported beyond six months.
Edit the file /etc/apk/repositories using an editor (nano for instance) and add (or uncomment) a line that points to the "community" directory, as in:
https://<mirror>/alpine/<version>/community
After enabling the community repository, obtain the latest index of available packages with:
apk update
The community repository was introduced with Alpine Linux version 3.3, and required to enable it to continue to use some former main packages.
