Hi,
I'm using virt-manager with Solus and get the error “You need to install openssh-askpass or similar to connect to this host”
I can't find it in Solus repos, so I tried 'kaskpass' but without success so far.
You can workaround this problem by starting virt-manager from a terminal sudo virt-manager --no-fork, then the password will be asked in the terminal window.
As far as I remember the openssh-askpass interface is "ugly-looking", maybe it would be nice to somehow get Budgie ask for the password instead, if possible ~
Cheers
