I recently downloaded tails 2.0. I verified the signature through Ubuntu. Through command line. It gave a positive verification. On shut down of the tails 2.0. The normal screen comes up where it say the display will power down and to remove the DVD or USB drive. But instead of the DVD drive getting ejected some script starts to run. I immediately shut it down by use of the power button. The same script came up every time I shut it down about 4 times now.
I double checked the ISO verification on the same tails (2.0) I downloaded it gave this
tails-I386-2.0 ISO untrusted valid signature. Valid but untrusted sighed by on 2016-01-26
On tails 1.8.1 it gives
tails -I386-2.0 ISO good signature sighed by on 2016-01-26
What should I do. Should I let this script run? Is this normal? Is it a one time thing? Is this because it is Debian 8 (Jessie)? Does this happen to your download as well?
