The Linux Mint crew has released LMDE 4 “Debbie” as their hedge against anything dramatic happening to Ubuntu that would limit their ability to offer Linux Mint and for those preferring the upstream Debian base. Linux Mint Debian Edition 4 is re-based against Debian 10 “Buster” and besides the updated packages has a number of other improvements to this second-class Linux Mint version.
With Linux Mint Debian Edition 4 there is finally UEFI SecureBoot support, automated partitioning support for LVM and full-disk encryption, home directory encryption is also supported, and other installation improvements.
