Sorry but for me, LMDE3 is phblished far too late, he'll have to go out 1 year ago.
cf : https://www.debian.org/News/2017/20170617.html
The freeze of Debian 10 Buster will be in 6 months...
Therefore, i will not test LMDE3 because its so late release makes no sense to me.
Otherwise Mint 19 Tara works fine.
Note that LMDE 3 comes with two installers:
Post-install, no matter what installer is used, both should be removed.
