"Unable to create io-slave" error on Kubuntu 20.04

  • 772

I am trying to attach a file in the "Send Fax" wizard of HP Device Manager (HPLIP 3.20.6).

In the window called "Select Files to Send", I click on the "Add..." button, and I get the error

Unable to create io-slave. Can not create socket for launching io-slave for protocol 'file'.

This has nothing to do with the specific location of the file I want to add, because I get the error before I can choose location.

Aside from this, the fax wizard works as expected.

kubuntu fax hplip
