Upgrade from Ubuntu 16.04 to 18.04 - improper use of do-release-upgrade

I started an upgrade from Ubuntu 16.04 to 18.04 but did not follow the proper procedure. The sequence of commands I executed are:

sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y
sudo apt-get autoremove
sudo apt-get install update-manager-core
sudo do-release-upgrade

At this point, instead of pressing "enter" to continue with the update I hit "ctrl c" and exited the above command, then I ran the following three commands:

sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y

The last three commands caused a number of updates to occur, and it looks like they were updates for 18.04 but I believe my computer is still running on 16.04

My computer still seems to run fine (I have not tried rebooting).

My question: Can I still complete an upgrade to 18.04? If yes, how do I do this? Or, have I really messed things up and it is best to leave things as is?

The use of `-y` with `dist-upgrade` is very dangerous.

You've not said if this is a server or desktop system, if it was a desktop system, I'd recommend just *upgrade via re-install* (ie. non-destructive re-install; where the lack of format triggers a repair installation, but using 18.04; also if internet is available during install, your *manually installed* or added packages will auto-reinstall if available for new release in Ubuntu repositories). To fix your situation you'd need work out where you were up to & continue from there; but it's not clear. What was machine doing when you hit ^C What did you see when you first ran `apt update`..

Your use of `-y` was very wrong in my opinion; you needed to read messages & deal with whatever was provided; where `-y` in your messages implied you'd already done your homework by checking before commands were executed, and corrected any problems before hand. The use of `-y` has made your situation I suspect, far worse & I'd read back what you agreed to with the `-y` and is there something you need to walk back etc... I'd opt for re-install if you didn't do your homework prior to `-y` commands being executed.

I see no problems with what you did.

With your commands you installed regular updates for 16.04. Then you cancelled a release upgrade.

Now you can run do-release-upgrade.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
