Using GParted to move up the start of an extended partition and of the enclosed logical partition, resulted in the error: *Unable to satisfy all constraints on the partition. *
**The solution was to disable the alignment requirement for the extended partition. Using an alignment for the logical partition enclosed in the extended partition was fine.
I post this here to remind me of the solution and in case someone else has the same problem. These are the best answers that I found leading to the solution:
