I can only access to LISH right now because something is broken. I am trying to get all the patches current. The issue appears to have started on 6/5 as things appeared to be working until that point.

I see the distro has reached EOL. I am trying to upgrade the distro, but it is demanding that all the patches are current.. and I cannot complete the upgrades due the previous errors.

Checking for a new Ubuntu release
Please install all available updates for your release before upgrading.

I never, personally, used the enterprise subscription, so I am not sure how these are in the list, unless added during patching. Either way their not accessible now. Is there an alternate path to get things current for patching?
