Hi, Sorry to copy-paste more install errors, but this one has been confusing me for a while: Summary: "The pkg-config package poppler-glib version >=0.12.4 is required but it could not be found." I don't know how to fix this, as "poppler-glib" is not a package (and not a dependency). Thanks in advance!
