centaurus and virtualbox extension

Hi,
on a fresh centaurus (Trinity) install, i installed virtualbox 6.1 . as on virtualbox website described.
Virtualbox runs fine, but installing the VirtualBox 6.1.10 Oracle VM VirtualBox Extension Pack via browser
the installer failed with exit code 127: Error creating textual authentication agent: Error opening current controlling terminal for the process (`/dev/tty'): No such device or address.

this error is not with q4os scorpion and virtualbox 5.2.

hope this is fixed in the next centaurus release.

thanks in advance, j

You likely need to have the "polkit-kde-agent-1" package installed:
$ sudo apt install polkit-kde-agent-1
and try to install extension pack once again.

Alternatively you can install the extension pack directly as root:
$ sudo vboxmanage extpack install <path_to_extension_pack>

Re: centaurus and virtualbox extension

Thanks for your fast response.
$ sudo apt install polkit-kde-agent-1 and a reboot did it!

I already knew the direct installation as root, so my intend for fixing is to prevent others from this issue.
Would be fine when everything works as it should.

Thanks again.

Re: centaurus and virtualbox extension

Anyway, we can recommend you more easy way to install Virtualbox in Q4OS using its dedicated tools:

$ sudo qrepoadd --gui
Select Virtualbox repository to add it to system including the proper keyring.

$ sudo apt update
$ sudo apt install virtualbox-6.1
