Release Notes: UBOS Linux Update 2021-12-14


To upgrade


If you are on an ARM device, and you are running the Nextcloud News app, you need to undeploy it first, otherwise the upgrade will fail. More details below.

To be safe, first create a backup of all your sites, with a command such as:

  • sudo ubos-admin backup --all --backuptodirectory ~

Then, update your device:

  • sudo ubos-admin update -v

Major package upgrades in this version

  • Mastodon
  • Matomo
  • Mediawiki
  • Nextcloud. Many Nextcloud accessories have been upgraded as well.
  • phpBB
  • Webtrees
  • Wordpress. Many Wordpress skins and plugins have been upgraded as well.

Bug fixes

The usual: fixed bugs and made improvements. You can find the closed issues on Github tagged with milestone ubos-apps-26.

Known issues

  • If after the upgrade, Nextcloud reports an “internal error” (out-of-memory error related to the database), restart mariadb. This is easiest if you simply reboot your Device.

  • The Nextcloud News app now requires 64bit-PHP. Lower-end (ARM) devices do not meet this requirement. Upgrading such a Device running the Nextcloud News app will fail, as the Nextcloud upgrader reports an error and keeps the installation in maintenance mode. To avoid this, it is best to redeploy the Site without Nextcloud News before the upgrade. Here is a possible sequence of steps:

    1. Determine the current Site JSON and save it to a file:

      % sudo ubos-admin showsite --json > site.json
    2. Edit that file, e.g.:

      % vi site.json

      by removing the line that reads: "nextcloud-news",. Save the file.

    3. Redeploy the Site:

      % sudo ubos-admin deploy -v --file site.json

    Then upgrade your device as usual.
