When attempting installing Linux Mint from a Live USB, it might fail after downloading updates. Here is how to solve it:
- Start installation. Continue wizard until last page (the one that asks for User account).
- Open console (
CTRL+ALT+DEL) - Type
sudo touch /target/etc/apt/sources.lists.new - Click Continue.
Note: If the above command fails, maybe the /target point is not mounted yet.
Simply click Continue button to start copying some files and then execute command again.
If you want to look other errors: less /var/log/syslog.
This was tested on versions: 17 and 18.
