Unable to start NCS - PI 3.5 cat: write errror: No space left on device

I was going to install the maintenance release for 3.5,  I performed an ftp backup, and then I stopped NCS via ssh so that I could create a VM snapshot.  When that was finished, I attempted to run NCS start, and that failed with the following message:

 

Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0
has been opened read-only.
Error: /dev/sr0: unrecognised disk label
cat: write error: No space left on device

 

I attempted to restore from the ftp backup, and that failed.  I then tried rolling back with the VM snapshot, but I am unable to start NCS because of the message above and I was wondering if anyone had any suggestions.  I do have a case open but I thought I would try this avenue as well.

 

Thanks!

Thanks for the help.  I came across the link below and there is a reference where someone rebuilt the wtmp folder so I tried that and it worked.

 

#enter shell:
shell
#get root
sudo su -
#write an empty new wtmp file (this can take a minute)
cat /dev/null > /var/log/wtmp
