Can't mount usb-drives in sys-usb based on a fedora-28-minimal template

[799]

Hello,

I have migrated all my VMs to fedora-28 based VMs and documented the exakt steps to do so as I want to write a howto for newbies coming from a fresh Qubes Installation to get a fully working production environment including newest templates, windows and maybe crossover.

After a clean installation of Qubes 4 I run into an issue using my newly created sys-usb qube.

sys-usb sees an attached harddrive but when I try to mount the drive (click on it) I get the following error message:

Unable to access "EXT-HDD2"

Not authorized to perform operation (polkit auhority not available and coller is not uid (0)

If I pass the USB-drive to my AppVM it will not be shown in the file explorer.

When switching back to the default fedora-26 based template for sys-usb everything works.

Those are the command/script to create my fedora-28-minimal based template for the sys-VMs.

# Install Fedora 28 minimal template
sudo qubes-dom0-update qubes-template-fedora-28-minimal

# make sure networking is available

qvm-start --skip-if-running sys-firewall

# clone template

qvm-clone fedora-28-minimal t-fedora-28-sys

# Install packages for sys-vms

qvm-run --auto --user root t-fedora-28-sys "xterm -hold -e 'dnf -y update && \
dnf -y install qubes-core-agent-qrexec qubes-core-agent-systemd qubes-core-agent-networking \
  qubes-core-agent-network-manager notification-daemon qubes-core-agent-dom0-updates qubes-usb-proxy \
  network-manager-applet  NetworkManager-wwan NetworkManager-wifi iwl6000g2a-firmware qubes-input-proxy-sender && \
  shutdown -h now'"

# shutdown all vms

qvm-shutdown --all --wait --timeout 120

# use the new template

qvm-prefs --set sys-usb template t-fedora-28-sys
qvm-prefs --set sys-net template t-fedora-28-sys
qvm-prefs --set sys-firewall template t-fedora-28-sys

# restart sys-vms

qvm-start sys-firewall sys-usb

QUESTION:

How do I fix the error "Not authorized to perform operation"

Can you reproduce the problem?

From https://www.qubes-os.org/doc/templates/fedora-minimal/#qubes-40 , it
looks like you might also need "dnf install
qubes-core-agent-passwordless-root polkit"?
