Include:Upgrading to latest release
When Alpine Linux is installed to hard drive, upgrading to a newer stable version is straightforward.
To begin, you need to update your /etc/apk/repositories file. Here are some shortcuts for doing so:
- Launch
setup-apkrepos
Enter e to edit /etc/apk/repositories. Change the version number by hand. - Or, edit the file in place. This is how you'd change v2.5 to v2.6:
sed -i -e 's/v2\.5/v2.6/g' /etc/apk/repositories
- Launch
Or you could do this manually: Edit the /etc/apk/repositories file using an editor (nano for instance) and if necessary, add references to the Alpine package repositories. In the example below, the file references the Alpine CD, so that if a requested package is available on the local media, it will be obtained from there instead of being downloaded from the remote repository:
Contents of /etc/apk/repositories
To upgrade, in this example, from version 3.3 to 3.2, simply change:
http://dl-3.alpinelinux.org/alpine/v3.3/main
to
http://dl-3.alpinelinux.org/alpine/v3.2/main
So that the file will look like this:
Contents of /etc/apk/repositories
http://dl-3.alpinelinux.org/alpine/v3.2/community
Above, only one possible repository is shown, however, http://dl-3.alpinelinux.org/alpine/
may also be replaced with any geographically close mirror from:
http://rsync.alpinelinux.org/alpine/MIRRORS.txt
Updating package lists
With the correct repositories file in place, the latest index list of available packages can be obtained with:
apk update
--update-cache
or -U
to another apk command, as in apk add -U ...
or apk upgrade -U
, has the same effect as always running apk update
immediately before the other apk command. Instead of auto-update it only if the index has not been updated recently.If you're upgrading from a version of Alpine before 2.3.0_rc1, ensure you have the latest available version of the Alpine Linux Package Manager first before upgrading anything else:
apk add --upgrade apk-tools
Next, upgrade all your packages:
apk upgrade --available
The --available
switch is used to force all packages to be upgraded, even if they have the same version numbers. Sometimes changes in uClibc require doing this.
