Release notes: UBOS Linux OS and apps update 2023-06-13

/releases/2023-06-13/release-notes/

Release overview

This update contains hundreds of updated and new packages, both on an operating system level and applications. There are a few bug fixes, but mostly this update consists of updated packages.

Both the “yellow” and the “green” release channel have been updated.

Notable app upgrades:

  • Nextcloud is now at version 26.
  • Mediawiki is now at version 1.39.3.
  • Decko is now at version 0.15.6.
  • Mastodon is now at version 4.1.2 (yellow channel only)

To upgrade

Warning

If you are running UBOS on an Amazon Web Services EC2 “t2” instance, do not run this upgrade. The now fairly old t2 instances do not support the newer Linux kernel we are using, and will fail to reboot. Instead, migrate your sites to a newer instance type (e.g. “t3”), such as by creating a backup of your sites to Amazon S3 with ubos-admin backup, and then restoring them to the new instance with ubos-admin restore.

To be safe, first check the status of your Device:

  • sudo ubos-admin status

and make sure everything is in working order. Then 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

As as so many packages are new, the upgrade can take a while.

Note

This upgrade can take a long time (hours), because some cryptographic keys need to be updated, and the key server we depend on can be very slow. If you don’t like this, first update your keys:

  • log on as root, and run pacman-key --refresh-keys, and then
  • run ubos-admin update --nokeyrefresh

This will take about the same amount of time, but your Sites will continue to be working while pacman-key is running. The actual update then can be much faster.
