no, the idea of snapshots is not done yet.
MintUpdate has been though a lot of chances lately to adapt it to LMDE;
Trying to answer your first question, why MU shows no updates availables and when you update in the terminal lots of them show up, well it's an old discussion here on forum: by defaulty MU has only level 1-3 enabled, so core libs, kernel are not updated; on the other hand if you update though the terminal, you update the hole system: there's the difference.
The recommended way to update?
- enable all 5 levels in MU;
- use synaptic;
- Code: Select all
apt-get update && apt-get dist-upgrade
Plenty of choice
