Tails could not determine whether an upgrade is available from our website.

This is probably caused by a network connection problem.

Check your network connection, and restart Tails to check for upgrades again.

If the problem persists, report an error and include in your report the debugging information that appears in the error message.

This error could also be caused by:

  • an error in Tails Upgrader
  • a failure or an attack on the Tor exit node being used, your Internet service provider, or our website.

Sending us a report is the best way to further analyse the error.
