[Bug 1743995] Re: Upgrade 17.04 to 17.10 not possible

[Jean-Baptiste Lallement]

You do not have to use this tone. I doesn't affect 'linux' because it is
not a problem with the kernel and it does not affect 'update-manager'
because it is not a problem with this tool.

It happens because:
1. you are trying to upgrade from an unsupported release (17.04 reached end of life on Jan. 13th)
2. you are using invalid entries in apt sources list (http://archive.ubuntu.com/ubuntu stable Release) not set by Ubuntu (any third party installer added it, or from the command line maybe?)

The upgrade from end of life release is documented on this wiki page:
https://help.ubuntu.com/community/EOLUpgrades

There is also a very good answer on askubuntu.com:
https://askubuntu.com/questions/91815/how-to-install-software-or-
upgrade-from-an-old-unsupported-release/91821#91821

Remove the invalid entry from your sources list files and follow the
instruction on the askubuntu post and you should be able to upgrade.

I'm closing this report because it is not a bug with Ubuntu.
