I tried different solution but it all failed,

First I tried to install Tails 2.4 to 8GB Kingston drive and it give error, 'insuficient free space', Drive is tested OK, no bad sectors, I then tried different usb slots - with same results. Then I tried to follow advice from forums to log in with password, I set password - tried to install - same result!

I used command line to install as SU, same error.

I then used 16GB kinston, exactly the same error. 32GB SD card - same result!

After that I setup VM and tried to install tails from VM, got this error:

Partitioning device /dev/sda
GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface 'org.freedesktop.UDisks2.Partition' on object at path /org/freedesktop/UDisks2/block_devices/sda1
Tails installation failed!
g-dbus-error-quark: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface 'org.freedesktop.UDisks2.Partition' on object at path /org/freedesktop/UDisks2/block_devices/sda1 (19)

So this is horrible, If anyone found the solution how to overcome this errors and install tails I would appreciate.

  • What method are you trying to use to write the ISO image to the USB drive? Jul 13, 2016 at 17:06
  • I use Tails installer following the guide here tails.boum.org

Had the same problem today.

After (!) getting the error:

  • open "disks".
  • Select your sdcard (be sure to select the right one - in your case /dev/sda/)
  • Select the first partition.
  • Click on the gear symbol.
  • select "Format partition"
  • select type "FAT" (should be already selected)
  • click "Format"
  • restart installer

Then it worked for me.
