The upgrade could not be downloaded.

This is probably caused by a network connection problem.

Check your network connection, and restart Tails to try upgrading 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, our website, or one of our mirrors.

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