Gimp conflict with MyPaint

[imatt.au]

When trying to install MyPaint (via Software Center) error occurred stating unmet dependencies.

Installed via command line using apt-get. apt-get advised that gimp would be removed if mypaint was installed.

After installing mypaint, and attempting to reinstall gimp, apt-get stated that mypaint would be removed.

Gimp (Snap version) is unaffected by mypaint installation.

I am unmarking this a duplicate. The other bug is closed in Ubuntu & isn't specific about this issue so let's keep this bug open.

[Erich Eickmeyer (eeickmeyer)]

@jbicha I agree, but I am not sure if this is really a bug with gimp since the problem is MyPaint's reliance on an older version of the library, and ultimately their failure to release a newer version that relies on libmypaint 1.3. We first approached this topic over 6 months ago (prior to Bionic's release) and it went nowhere. This is frustrating since we want to get MyPaint back in Ubuntu Studio, but we're stuck with them being not coinstallable.

@immatt-au This is a known issue, see http://ubuntustudio.org/2018/05/regarding-gimp-2-10/ and http://ubuntustudio.org/2018/10/ubuntu-studio-18-10-released/ (specifically in "Other Changes). That said, thanks for this report as it does bring more attention to the matter. Additionally, according to the github issue linked above, it is a known issue in Fedora as well.

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

[Wladimir J. van der Laan (laanwj)]

Same issue here on Ubuntu 18.04
I guess it's time for me to check out the snap system if I want to use both applications

ubuntu is on 19.04 and still this bug exist...amazing incompetence

@cs-. Such belittling comments are inappropriate in a bug comment. If you have nothing to contribute, please refrain from making such comments in the future.

[Malix (malix0)]

Now that MyPaint 2.0.0-alpha is available, it's worth packaging it?

[Erich Eickmeyer (eeickmeyer)]

@malix0 The MyPaint package is inherited from Debian. They typically do not package alpha or beta packages, but only final releases since the focus is on stability as opposed to having the latest thing. Therefore, this is likely not to happen until MyPaint has released 2.0.0.

[Jeremy Bícha (jbicha)]

I think this will finally be fixed in time for Ubuntu 20.04 LTS.

[Jeremy Bícha (jbicha)]

To give a few more details, mypaint was removed from the 20.04 archives for a different issue. mypaint 2.0.0 is now in the NEW queue where it will probably be accepted soon.
