I am on a Chromebook and am running a chroot. My Ubuntu version is 16.04.6 I want to upgrade to a newer version. Is this possible? If I look online, it says to open a program called update manager. For me, that program does not exist and when I type in the command to get that program, it says HTTP quit unexpectedly. Can anyone help?

  • I'm pretty new to this stuff so you may have to explain the solution in detail – Shubh Singh May 31 '19 at 03:34

  • Just remember if you don't know what you are upgrading to, you will definitely be in for a surprise. Perhaps a pleasant one, perhaps a rude awakening and regret that you can't downgrade back Ubuntu 16.04.6 LTS. I would urge you to understand what it is you will be upgrading to. – WinEunuuchs2Unix May 31 '19 at 04:27

Is there a program called "Terminal"? Open that and type sudo apt. There will be shown a list of most used commands or at least a list of commands. You are looking for the dist-upgrade command or the "sudo do-release-upgrade" command.

Check if The standard Ubuntu Software application can be run and go to the updates section. You can select many software sources here. Select all sources and newer versions and apply. Then try updating again. If you cant even update an upgrade is unlikely too. Try this first. enter image description here
