Bug#1033617: libopenexr-dev: Cannot just upgrade libopenexr-dev to 3.1.5-4 because of file conflict with older version of libilmbase-dev

[Felix Stupp]

for documentation purposes, I now fixed the issue for my systems by force-removing the old package first with dpkg and then installing its replacements with markauto:

sudo dpkg --remove --force-depends libilmbase-dev
sudo aptitude install lib{imath,openexr}-dev+M  # or apt install --mark-auto lib{imath,openexr}-dev
