Comment 3 for bug 1865351

The poppler update is tricky, as usual they bumped the soname and did some code changes that impact other projects. Testing in a ppa e.g libreoffice fails to build, and looks like upstream didn't fix that yet. Same of e.g extractpdfmark
https://launchpadlibrarian.net/469668101/buildlog_ubuntu-focal-amd64.extractpdfmark_1.1.0-1ubuntu3_BUILDING.txt.gz

We might look at backporting specific fixes, keeping away from API changes for this cycle
