Might be missing SSL support in some library or tool, or a failure to access that particular server - the file-uri plug-in can be built to use through gvfs, libcurl or wget, cf. https://git.gnome.org/browse/gimp/tree/plug-ins/file- uri/Makefile.am?h=gimp-2-8#n26
My bet for the Ubuntu packages is on gvfs, as the gimp package doesn't seem to have a dependency on libcurl or wget. I'm not running Ubuntu and thus can't check, though. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/1649428 Title: Cannot open file from https location (URL) Status in gimp package in Ubuntu: New Bug description: If I try, I get this GIMP message: Opening 'https://[...]' failed: Could not load 'https://[...]': Failed to open file 'https://[...]': open() failed: No such file or directory Most of the time, I can manually edit the URL to read http://[...] and I can open the document as expected.
