I'm running Fedora 28 and trying to set up a live USB to run CloneZilla and backup my system. Problem is, I can't get into my USB in any way. Basically everything i try throws up the error

Not authorized to perform operation (polkit authority not available and caller is not uid 0) (udisks-error-quark, 3)

I've been Googling my little heart out and can't find anyone who seems to have a matching situation or a solution that works for me. My drive shows up in parted and fdisk and disk manager and Nautilus. I even tried using sudo mount and I got nothing. Flash drive is brand new, just bought it tonight, so no wear or corruption or anything.


Edit: I forgot to mention that polkit is indeed installed, so I don't think there should be an issue there, unless something got messed up. I have also tried rebooting, to no avail.

Is polkit running? Please run: sudo systemctl status polkit.service. If not you can start it: sudo systemctl start polkit.service. To enable it on every reboot run: sudo systemctl enable polkit.service.

/usr/libexec/polkit-gnome-authentication-agent-1 must be running too.

Anyway you should be able to mount your device as root, e.g. : sudo mount /dev/sdb1 /mnt

I have same problem except no "(udisks-error-quark, 3)" when inserting my old sandisk 256mb. This has been "fixed" by windows 8 scan so that I could use it there. Restart polkit gets same error. Mount as root "mount" shows:

/dev/sdb1 on /mnt/flash type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro)

I'm running Fedora 28 LXDE - updated the 23rd. Did not have this problem with Fedora 26. I have no file "/usr/libexec/polkit-gnome-authentication-agent-1"
