After an upgrade from F26 to F27, evince fails to open djvu files, even with installed evince-djvu subpackage.
Workaround : # rpm -e djview4 djview4-plugin djvulibre djvulibre-libs # dnf install djview4 djview4-plugin djvulibre djvulibre-libs (doing that for each rpm separately is not sufficient)
ah got it. the problem is with djvulibre postinstall scriptlets, that don't rerun update-mime-database after package removal (moreover the preuninstall scriptlet fails with a non existing script /usr/share/djvu/osi/desktop/register-djvu-mime) . reassigning to djvulibre.
This is a duplicate of #1513188 "multipage djvu files are misidentified".
