• Wait for tag/24.04 to be finished
• Wait for multi-arch builds of this PR to successfully finish
• Prepare draft mail to technology-webkit, announcing the image change (new base image, new sysprof, etc.)

I guess my question is what is the main value of this bump?

24.04 is an LTS release, so it will have a lot of support for a while, and we want to target that version until April 2027

Good question 😆 I vaguely remember that I could not easily get a newer sysprof version to build, without having to build additional components in new version that the system usually provides.

However, don't take my word on that, it's too long ago I would need to retry.

sysprof makes sense, I recently backported it in Yocto and it truly depends on the latest of everything...

I'm not sure that one project is important enough to move everything over though.

I think alone the compiler versions that are more recent are a reason to update since this is meant to be a developer SDK.

It also simplifies using perf for the people that use Ubuntu 25.04 on their host - but that is rather a weak argument 🤣

I discovered three distinct issues related to GCC 14 that I already fixed upstream in preparation for the bump. I'm already using this image since a month on my main development machine without a problem, just to give some additional data points.

I was under the impression that flatpak SDK was also using quite recent versions of everything - so I didn't give this much thought before starting the bump effort.

We have access to basically every clang version. So its just a newer GCC toolchain (losing the older version).

It's not my intention to fight against it, just thinking about reasons for it.

That's correct, we can access newer clangs, but not gccs.
I'll bring this up on tech-webkit, for further discussion to make sure we don't miss any important pro/con.

Another pro: You cannot build epiphany main on 24.04 any longer also.

Ubuntu 25.10 was released a month ago (9th October)

I guess that if we switch the base version, then it already makes sense to move to 25.10 instead of 25.04

[nikolaszimmermann]

Actually we probably need to wait for the next LTS release -- otherwise the APT repos will disappear if supports ends, etc.

[nikolaszimmermann]

We can soon resume the work, the next LTS is due in exactly one month.
