I was trying to upgrade to Ubuntu 18.04 from 17.10, and I used the Ubuntu Software / updates, but it gave an error. Also my laptop has logged me out of sessions/restart from Ubuntu login screen twice.

Is this due to not being on 18.04? Also I have used sudo to add Mint desktop repository as an option.

I see this error as shown in the photo:

tpw tpw0: A TPM error (325) occurred stopping the TPM

Ubuntu's own instructions specify how to upgrade from 17.10 on a desktop system:

Press Alt+F2 and type update-manager -c into the command box.

Update Manager should open up and tell you that Ubuntu 18.04 LTS is now available. If not you can run /usr/lib/ubuntu-release-upgrader/check-new-release-gtk

Click Upgrade and follow the on-screen instructions.

Comment from June 2019. The above suggestion flat-out doesn't work any more. The update-manager fails to connect. The check-new-release-gtk app fails. You cannot even run apt-get update or apt-get upgrade and more Here are screenshots from trying to do all of this on a freshly installed VirtualBox VM of the ubuntu-17.10 desktop ISO

It would appear that old versions of Ubuntu and their users have simply been dumped in a ditch and abandoned. These are the links to the screenshots.

apt-get upgrade fails apt-get update fails, too check-new-release-gtk fails ... ... and then core-dumps update-manager also fails

In summary: you can't upgrade. The best you can do is backup all your stuff, all your customisations, all your additional software configurations. Then remember all the additional software and packages you installed. Once you've done that you have to over-write your installation with an LTS version and then spend days trying to reconfigure all the new stuff with your old settings and whatever third party software that will run on the later version.
