The issue you are facing: I upgraded my router and that led to some connection drop for nextcloudPi on my raspberry Pi every hour until it fully stopped connecting. It became completely inaccessible from my computer or phone. At that time, I tried to install a fresh version of nextcloudPi on my SD card as I have my data in a USB SSD drive and the backup in a USB hard drive. I canât remember how I setup the backup initially but it seems I went for dateless backup with snapshot. At this time, this is what I am trying to do.
Step 1 - Boot up with the fresh install of nextcloudPi - successful
Step 2 - Enable NC Auto mount via web interafce - successful
Step 3 - Enable SSH via web interface - successful
Step 4 - Grab the backup drive path and the tar file location via SSH - successful
Step 5 - Run nc-restore via web interface after pasting the link to the tar file from the backup drive - failing
This Step 5 has failed multiple times with the below error. Grabbed it from /var/log/ncp.lg
