I am currently at 20.10 The systems are upgraded both in terms of hardware and software since at least 14.04 , maybe before - not only LTE, but both .04 and .10 releases.
Having upgraded to very fast hardware (M2 SSD / i9 10900) it would be very nice to "fresh up" the system, maybe remove tons on unused packages , clean some configuration...
Is there a guide on how to do so ? - I guess it is not as simple as keeping whole "home" , because then lots of old system stuff is kept as well..
