Dual or Triple Boot - can not have 2 computers with the same name message

Just posting in case others are experiencing similar.

It looks like if one Dual or Triple Boots, as I do between Ubuntu Linux, macOS Big Sur and Windows 10, and one is connecting to other PC's via each of the 3 OS's that one happens to be booted into, then one needs to give each OS/Partition its own distinct name, otherwise one is likely to get an error message stating something like can not have 2 computers with the same name

Solution change computer's name via the Synergy GUI.
