Unable to install Ubuntu 18.04 from 17.10

I’m trying to upgrade Ubuntu but there is no new release available.

Output of lsb_release -a:

No LSB modules are available. Distributor ID: Ubuntu Description:    Ubuntu 17.10 Release:    17.10 Codename:   artful 

Output of sudo do-release-upgrade:

Checking for a new Ubuntu release No new release found. 

Also, when I do Alt+F2 and update-manager -c it says “Failed to download repository information”.

Output of cat /etc/apt/sources.list:

deb http://archive.ubuntu.com/ubuntu/ artful main universe restricted multiverse deb http://security.ubuntu.com/ubuntu/ artful-security universe main multiverse restricted deb http://archive.ubuntu.com/ubuntu/ artful-updates universe main multiverse restricted 

Thanks for any help.

I Cannot Update Past 17.10

This is kind of a long story, but I’ll try to keep it simple and to the point.

My hard drive with Windows 10 on it broke. I’m not sure why, and the actual hardware is fine, but the installation was beyond repair. I was trading hard disks between computers as I was upgrading to a new machine, and must have done something wrong that caused it to throw a fatal fit. Whoops.

In any case, I could boot of a live USB, but installing CentOS from a UEFI bootable didn’t work (said something about not being able to activate the port). Then I remembered all the Linux distros I had lying around which I burned on disks a few years ago. I popped in the Ubuntu disk, went through the installation process and everything was fine. Almost everything.

The trouble is, I’m on version 17.10, and the software updater isn’t pushing any new system updates to me. Whenever I look for packages in the terminal, it can’t find them. I don’t know if all my problems will be solved by updating to the latest version, but it’s a start.

What should I do next?

Thanks!

P.S. I’m connected to the internet via cord and I can also access it wirelessly.

Unable to Upgrade to Ubuntu 18.04 From Ubuntu 17.10

I’m trying to upgrade my Ubuntu release from 17.10 to 18.04 without success.

do-release-upgrade is returning the following error:

Checking package manager  Can not upgrade   Your python3 install is corrupted. Please fix the '/usr/bin/python3'  symlink. 

I removed all my update-alternatives configuration for python, then I tried to reinstall python3 but it didn’t work.

I tried also to completely remove python3 and then install it again without fixing the issue.

Just for your information /usr/bin/python3 symlink seems to work fine:

neoben@neoben-samsung:~$   /usr/bin/python3 Python 3.6.3 (default, Oct  3 2017, 21:45:48)  [GCC 7.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>>  

Do you have any suggestion to solve the problem?

Thanks!
