Ubuntu 24.04 still using Ruby 3.1 close to EOL

[Hadmut Danisch]

Hi,

I just had a view to a nightly build from Ubuntu 24.04, and saw, that it still uses Ruby 3.1.

But have a look at

https://www.ruby-lang.org/en/downloads/branches/

Ruby 3.1 will reach end of full support on 2024-04-01 and be limited to security fixes til 2025-04-01. You cannot take this into an LTS release that is supposed to work for at least 2 years.

For 24.04 you would need at least Ruby 3.2 to get at least security fixes until Ubuntu 26.04, and Ruby 3.3 to get support for the full lifetime of Ubuntu 24.04.

Thanks for reporting.

I don't know if there's a tracking bug or plan outlined somewhere, but when checking I found the packages linked below. Seems like there is some work going on in noble-proposed regarding Ruby 3.2:
https://bugs.launchpad.net/ubuntu/+source/ruby3.2/3.2.3-1
https://bugs.launchpad.net/ubuntu/+source/ruby-defaults/1:3.1+1

Noble will be released with Ruby 3.2 as the default. Right now, many transitions are ongoing and because of that the ruby one is not complete yet. But do not worry, users will have Ruby 3.2 in Noble.

Will Ruby 3.2 then upgraded to 3.3 during lifetime of noble, once support for 3.2 has ended?

[Lucas Kanashiro (lucaskanashiro)]

No. Ruby 3.2 will be supported by Canonical during lifetime of Noble. We do not change default interpreters in stable releases.
