We are proud to announce version 24.04.2 of Subiquity, supported on Ubuntu 24.04.x LTS. Subiquity 24.04.2 is included in the Ubuntu 24.04.2 live-server ISO, and is now live on the 24.04/stable channel. Also, Ubuntu Desktop Bootstrap on Ubuntu 24.04.2 includes this same version of Subiquity.
What's new in Subiquity 24.04.2
Ubuntu 24.04.2+ LTS snap stable channel is 24.04/stable
Please see the 24.10.1 release notes commentary about changes to snap channels, as it also applies here (and all future versions). The summary is, broadly speaking, only select items are being backported to the 24.04.x series, and those backports are almost entirely bug fixes.
The version number of snaps for the 24.04.x LTS series now matches those of the ISO versions - as we are releasing Ubuntu 24.04.2 LTS, the Subiquity matching version is 24.04.2. While this version number appears to be older than the previous one offered with Ubuntu 24.04.1 LTS, it starts with the same Ubuntu 24.04.1 Subiquity codebase and adds additional bug fixes.
Unlike previous releases, this version is not being made available on the latest/stable snap channel. Instead this is on the 24.04/stable snap channel, and this ISO and future Ubuntu 24.04.x LTS ISOs will offer by default new snaps from 24.04/stable. Refresh behavior may be customized by autoinstall and by the kernel command line option subiquity-channel=channel. The latest/stable snap channel will be updated with future builds from interim releases like Ubuntu 25.04, and future .0 versions of LTS releases like Ubuntu 26.04 LTS.
