I have a DVD of my system and I have changed the partitions to use a smaller drive as sda.
I have a 3GB '/' and about 6GB 'home'
On the second drive, sdb, I have /home/user/Downloads,opt,tmp,usr,usr/local,and var, with spaces of-10GB,5GB,5GB,10GB,5GB,5Gb
The usr partition has 9.9GB asvailable
Swap space is 12GB. and ram 4GB.
I have no partition size of 8.4GB.
What does the error:---'Not enough space available (8.4GB available whilst 9GB are needed'---?
