I installed the Okular snap from the KDE channel.
Everything works great, but when I try to print a file I get an error:
Could not print the document.
Detailed error is "Could not find a suitable binary for printing. Make sure CUPS lpr binary is available".
Please report to bugs.kde.org
I installed cups-bsd and have the lpr file in /usr/bin/lpr. This is on Linux Mint 18.3.
Any suggestions would be appreciated.
You should report a bug, okular seems to not use the “cups-control” interface
@orga What would be the best place to report a bug? The okular snap page page just directs me to kde.org. Is there a github group with repositories of all the snaps, maybe?
well, the error message above (in your first post) would be what i’d take as authoritative for bug reports …
so bugs.kde.org and looking for the okular page there …
Great, thanks for the link. I’ll file a bug report with kde.
You might also want to suggest the snap’s maintainer that they request auto-connection for that interface (once they’ve added it), similar to what was done for the evince snap.
There is a patch by Harald Sitter which should fix the underlying problem, but it is blocked by another issue with Qt 5.10.
As @oSoMoN said, this will also require getting snap’s maintainers to approve auto-connection for the cups interface.
