xsane and gimp packages need updating

I tried to install Xsane on 20.04 using apt-get.

It fails because "you have held a broken package".

The failed dependencies are

libgimp2.0 --> libgegl-0.4-0 --> libopenexr23

The last of these is uninstallable because the current version is libopenexr24.

Someone either needs to update the repositories to rebuild libgimp2.0 against
libopenexr24, or to put scanner software under snap.

Note that gimp installs under snap, but not under apt.

Someone needs to make some executive decisions decisions. It looks like there may be
a fatal divergence of best practices here. Good software requires discipline!
