  4. When asked whether to keep or replace configuration files, choose to replace them.

Additional info

  • Although Linux Mint 18.2 features a newer kernel, this upgrade does not change the installed kernel. If you need the updated kernel, you can install it yourself any moment.
  • Same goes for the choice of display manager or the software selection. Brasero won’t be removed and MDM won’t be switched for LightDM on your behalf. You can decide to make these changes, but you certainly don’t have to.
  • It is recommended to disable the screensaver before upgrading. If the screensaver activates during the upgrade and you’re unable to log back in, switch to console with CTRL+ALT+F1, log in, and type “killall cinnamon-screensaver” (or “killall mate-screensaver” in MATE). Use CTRL+ALT+F7 or CTRL+ALT+F8 to get back to your session.

How to switch from MDM to LightDM

Warning: This is not recommend for novice users.

First, install LightDM by typing the following commands in a terminal:

apt install slick-greeter lightdm-settings

When asked to select a default display manager, select LightDM.

Then, remove MDM and reboot by typing the following commands in a terminal:

apt remove mdm

sudo reboot

That's it. Source: Mint Blog.
