en	Automatic upgrades are broken from Tails 4.14 and earlier.

en	To upgrade from Tails 4.14 or earlier, you can either:

en	Do a [[manual upgrade|doc/upgrade#manual]].

en	Fix the automatic upgrade from a terminal. To do so:

en	Start Tails and set up an [[administration password|doc/first_steps/welcome_screen/administration_password]].

en	In a terminal, execute the following command:

en	torsocks curl --silent https://tails.boum.org/isrg-root-x1-cross-signed.pem \ | sudo tee --append /usr/local/etc/ssl/certs/tails.boum.org-CA.pem \ && systemctl --user restart tails-upgrade-frontend

en	<div class="note">

en	This command is a single command that wraps across several lines. Copy and paste the entire block at once and make sure that it executes as a single command.

en	</div>

en	Approximately 30 seconds later, you should be prompted to upgrade to the latest version of Tails. If no prompt appears, you might already be running the latest version of Tails.
