Starting Tails 5.5 testing which has been upgraded from Tails 5.4 brings up the error unable to start persistent storage, start tails and send an error message. On starting Tails, the persistent storage was unlocked, the wifi settings within the personal storage were retained and the wifi was connected automatically. The persistent folder was availble and documents within were readable etc.
Nothing else was in the persiatent storage. I was able to change the password and then rebooted and started tails again. Got the same persistent storage message with the new password.
Small problem I know , but a problem all the same..
