In ubuntu 20.04 LTS (and since 18.04 LTS) I have used Money Manager Ex
to keep track of personal finances.
The advantage of this package available from the standard ubuntu repo's is the way it can handle transfers from one account in one currency currency to another (in my case transfers from a sterling account to a euro account).
I can't seem to find Money Manager Ex (mmex) in the repo's for MATE.
Can anyone advise on how to obtain this excellent application for MATE 21.04?
