Upgrading from older versions
Upgrading from 2.0 or 1.10.x to Alpine Linux 2.2 and later
Since the apk tool has been significantly changed you need to download and install manually the latest version of apk-tools-static. We also install busybox-static just in case something goes wrong.
If current version is 1.10.x remove GNU Wget before attempting an upgrade:
apk del wget
Download busybox-static and install it:
wget http://nl.alpinelinux.org/alpine/v2.2/main/x86/busybox-static-1.18.4-r3.apk apk add busybox-static-1.18.4-r3.apk --update-cache
Download apk-tools-static and install it:
wget http://nl.alpinelinux.org/alpine/v2.2/main/x86/apk-tools-static-2.1.0-r1.apk apk add apk-tools-static-2.1.0-r1.apk --update-cache
Change repositories:
Contents of /etc/apk/repositories
Proceed with update and upgrade:
apk.static update apk.static upgrade --available
The --available switch is used to force all packages to be upgraded, even if they have the same version number, due to changes in uClibc.
Reboot the system to load new kernel
sync reboot
