FFe: darktable 2.6.3 in focal needs update to 3.0.1

[layingback]

This is a request to update darktable deb to match the snap ;)

The biggest new features to warrant it:
- UI rework; everything is now themable, and it works properly on high-DPI screens
- 'filmic RGB' module as a new option to old global tone-mapping modules
- a new culling mode

and more, full release notes at
https://github.com/darktable-org/darktable/releases/tag/release-3.0.0

This also pulls in the first bugfix release, plus a couple of commits from git to fix some minor regressions found since.

--- original description: ---

Ubuntu 20.04 Focal Fossa LTS still only has darktable 2.6.3 in the official repositories.

darktable 3.0.0 was released Dec 24, 2019, and darktable 3.0.1 was released March 09 2020.

( darktable feature releases are traditionally released each Christmas. )

Please note that darktable 3.x is NOT backward compatible with darktable 2.6.3. So there is no way for a user of a more current version of darktable to even use darktable 2.6.3. A supplement problem is that running 2.6.3 when you have a 3.0.x db (eg. if upgrading Ubuntu to 20.04 in place) results in a totally silent fail at load. Only if run from a terminal do you see the '... db is too new ... Aborting ...' message.

I'll submit a post to <email address hidden> re this

Darktable is a package that is synced from upstream Debian. Even if 3.0.1 were to land in Debian today, we would need a Feature Freeze Exception (it contains new features) and a Sync Request in order to get it into the repo in time. Unfortunately, that's not likely to happen.

Long story short, it's too late to get it into Focal.

I *might* be able to get it in the Ubuntu Studio Backports PPA, but I'll admit, that's not a priority right now.

you can find dt 3.0.1 plus fixes on my ppa:
https://launchpad.net/~tjaalton/+archive/ubuntu/ppa

maybe there's still a chance to get it in focal

Status changed to 'Confirmed' because the bug affects multiple users.

[Erich Eickmeyer (eeickmeyer)]

@tjaalton if you can do the upgrade, be my guest. In other words:

As flavor lead of Ubuntu Studio, I approve this exception.

Removed assignee as tjaalton has already uploaded this.

This bug was fixed in the package darktable - 3.0.1-0ubuntu1

FWIW, Upstream and Debian-"unstable" have now released 3.0.2 ...
May be worth Updating now, in any-case keep an eye on upstream bug-fixes ongoing...

[Erich Eickmeyer (eeickmeyer)]

At this point, it is impossible to get an update to 3.0.2 into the Ubuntu archives. Final Freeze happened on Thursday, which means nothing enters or leaves the archives aside minor bugfixes for known bugs. This "update" also includes some new features (meaning the version bump should've been more significant than a meer bugfix "point release"), meaning it would absolutely not be allowed as Feature Freeze Exceptions aren't allowed after Final Freeze.

I'm afraid that due to the new features, even a Stable Release Update is out of the question as those are simply for bugfixes. That said, I might be able to backport it into the Ubuntu Studio Backports PPA.

[Simon Iremonger (ubuntu-iremonger)]

Thankyou for helpful answer, from what I can see new-features are minor, and there are likely to be many significant bugfixes ongoing that will need including one way or another.

In any case, I note neither focal 3.0.1-0ubuntu1 package, nor debian-unstable 3.0.2-1 package succeed in compiling atop bionic18.04 system... In both cases all the apparent dependencies can be satisfied (e.g. backported debhelper, likely nothing else apparently needing backporting).

Definitely worth making some PPAs with a view to bionic-backports in my view!. Can create a separate bug-report if needbe.

With many thanks,
