Description Vincent D 2021-04-10 16:42:34 CEST

It is not possible to print in evolution as packaged in mageia 8.

It is due to a bug in webkit and sandboxed code for printing, see:
- https://gitlab.gnome.org/GNOME/evolution/-/issues/1141
- https://bugs.webkit.org/show_bug.cgi?id=202363


How reproducible:
Try to print a mail, either on a real printer or in a pdf file. Evolution shows an error message (like: The printer replied “Error opening file â/home/XXXXXX/Documents/testout.pdfâ: No such file or directory”.) and nothing happens (no file created nor printing on a printer).

Steps to Reproduce:
1. Launch evolution program.
2. Try to print a mail, either on a printer or in a pdf file.


Possible workaround: add "export WEBKIT_FORCE_SANDBOX=0" in the file ~/.bashrc and restart the user session. It will then affect all gtk webkit based applications.

Please follow the progress of this bug to solve it when possible.

Thank you for the report, the references, and the workaround.
"Until we manage to fix this, you should not enable the sandbox if you need printing to work." They talk of 'WebKitGTK', but I cannot find anything of that name chez Mageia, the nearest being:
 webkit2
 lib64webkit2gtk4.0_37

As for the workaround, it begs the question of where the 'sandbox' is being invoked.

Assigning to the Gnome people.

We have the errata entry also in Mageia 9 currently.

But does it work in Mageia 9 without the workaround and errata 9 entry be removed?
