Access Datastore failed after update PVE 6 to 7 and PBS 1 to 2

[tanaka]

Hello,

After the update, I have the message "pve-backup: error fetching datastores - 401 Unauthorized (500)". Everything works before update but I have some issue during update like Grub boot problem. I change the root password to facilitate the access of IPMI/KVM console.
Is someone can help me please ?

Regards,

Ok the solution was to modify the password in /etc/pve/priv/storage/your-pbs-storage-name.pw
