Hi,
is it safe to add the https://build.opensuse.org/project/show/graphics repository and do a zypper -dup / switch packages to get the latest Gimp 2.10?
Thanks.
in theory yes but in practice don’t do it a full vendor change might replace other packages which you might want to keep as the graphics repo is large
if all you want is the newest gimp and inskape just add the repo and upgrade those packages you can use the versions tab in yast or the --from switch with zypper or use the version number
try
zypper ar -f http://download.opensuse.org/repositories/graphics/openSUSE_Leap_15.0/graphics.repo
zypper in gimp-2.10.2 inkscape-0.92.3
note the version number (those are the current versions in the graphics repo if they get updated use the updated versions) in gimp and inkscape without using the version numbering zypper will not install newer packages from different repo’s
you will probobly have to do a vendor change to quite a few packages to keep dependencies but I wouldn’t recommend doing a full vendor change
