So, I accidentally messed up my Linux Mint 18 admin account, deleting cinnamon-settings, making it impossible to login to my user account. I booted up from a clean Linux Mint USB, and am probably going to wipe my SSD with all my previous data. There are several large files (in the ~/.local/share directory) which I would like to transfer to the new install. Is there a way to do this? Thank you in advance.
Have you tried the login command from your terminal once you've logged in as administrator? That is, your account still exists correct?
$ login user
but replace user with whatever your user account is. Likewise, you can exit the user account with simply
It might be a good idea to create a new account. This is how I always do it: https://www.linkedin.com/pulse/20140502074357-79939846-adding-a-new-user-in-kali-linux
Then recursively copy all your folders, sub-folders, and files to your new account.
$ sudo cp -rf ~/.local/share /path/to/your/new/account
Now try logging in as the new user you created.
