[Tails-testers] Tails 4.19~rc1 tests

Hi all,
I ran tails version 4.17 before installing 4.19 rc1. I had troubles on updating the CA certificate for installation (need to manually edit the trusted CA file downloading the full chain from trails.boum.org). After that, successful update.
However now when connecting I receive an error message about the signing key certificate that cannot be verified.

Additionaly I found come strange behaviours:

1. when turning off PC and then reboot with Tails the wifi is not available (no icon or function in the upper right corner and neither in the settings pane wifi is listed). However if reboot the wifi function is visible and no more issues occours. I noticed this strange behaviour since version 4.17.
If you need laptop or wifi card model let me know.

2. Reboot works fine but shutdown seems to freeze

I'll do some other tests.
Thank you a lot,
Brian
