The bridge mode fails if the system clock is incorrect. To prevent this problem, correct the system clock before connecting to the network. To do so:
Set up an administration password when starting Tails.
Right-click on the system clock in the top navigation bar and choose.
Click thebutton and enter the administration password from step 1.
Adjust the time to be the correct time in UTC (use the same difference with your local time as observed usually in Tails).
See the current list of known issues.
If your Tails does not boot after an automatic upgrade, please upgrade your Tails manually.
The next Tails release is scheduled for January 26.
