Upgrading to Cumulus Linux 2.5.z



How do I upgrade to Cumulus Linux 2.5.z?


  • Cumulus Linux 2.5.z ONLY


The best upgrade steps can be found in the release notes for the version to which you want to upgrade.

You can upgrade to Cumulus Linux 2.5.z in two ways:

  • Using apt-get
  • Using cl-img-install

Using apt-get

apt-get upgrade can be used to upgrade to an X.Y.Z release from an earlier X.Y version. For example, from 2.5.1 to 2.5.3. Run the following commands to upgrade Cumulus Linux:

cumulus@switch$ sudo apt-get update
cumulus@switch$ sudo apt-get dist-upgrade

Then reboot the switch.

Using cl-img-install

apt-get cannot currently be used to upgrade to an X.0 or X.Y release.

To perform an upgrade using cl-img-install, run cl-img-install providing the location of an update image on the local filesystem or network.

cumulus@switch:~$ sudo cl-img-install

Caution: Installation via cl-img-install is destructive. All files and data in the alternate slot will be erased.

For more information on the use of cl-img-install, refer to the image management chapter of the user guide.
