Bug 1995728

Hi Samuel,

thank you for reporting the issue!

I'm able to reproduce the behavior via CUPS Web UI and adding liblouis-devel as a dependency offers more choices in the dialog as you've told.

Reproducing via CUPS Web UI:
localhost:631 -> Administration -> Add printer -> Local printers: CUPS-BRF (Virtual Braille BRF Printer) -> continue -> continue -> Make: Generic -> continue -> Model: Generic Braille embosser, 1.0 (en) -> Add Printer -> Braille transcription -> click on the scroll menu next to 'Braille transcription' label

Although Braille transcription now offers more transcriptions after adding liblouis-devel, the printing itself doesn't work because scripts from liblouis-utils are missing, and selinux is blocking cups-brf from creating BRF dir and files in it in home directory.

I have a working sample of selinux policy right now and I will submit it upstream.

I'll close this bug once all is in place and braille printing will work in the basic scenario.

Sent a PR to selinux-policy https://github.com/fedora-selinux/selinux-policy/pull/849 .

The cups-filters related fix lives on private-zdohnal-devel branch of cups-filters, still waiting for selinux...

The selinux-policy PR got into rawhide, so I can build a new cups-filters release there. But F34 and F35 don't have the selinux fix, so I've filed a bug to selinux-policy to coordinate the work (the bug is in 'depends on' field).

Built in rawhide for now https://koji.fedoraproject.org/koji/taskinfo?taskID=80792145 .

This change adds 5 new dependent packages and 11MB on disk (3MB download):
antiword
liblouis
liblouis-utils
liblouisutdml
liblouisutdml-utils

Can it be made optional or a separate subpackage? While I wholeheartedly support enabling this feature, most users don't need Braille printing.

They are optional, the cups filters can cope with them missing and fault back to trivial rendering.

That being said, I am surprised: what is the package that is most contributing to the size? Is that liblouis itself (and its tables which weigh ~10MB). liblouis is already mandatory for all blind users using the Orca screen reader. Is that not available by default?

Hi Dominik,

I'll try to create a subpackage next week if needed - it will be recommended by the main package, providing you a have how to install cups-filters without it.

But it would be great if you create a separate bugzilla to track this, thx!

That sounds perfect! Thank you.

Yes, it's liblouis.

It is, but it can be uninstalled. On my machines, I always remove all packages
that I don't use and that are not strict dependencies. orca is one of those.
Uninstalling orca saves me 14 packages and 49MB on disk.

I'm pretty sure I'm not the only one to prune unnecessary software from their
machines. In my case, I do it primarily to limit the number of potential
vulnerabilities (not installed=not affected) on my machines as well as to
make updates faster (not installed=no need to update).
