SOLVED. Thank you, Thomas.
I already had
root# apt-cache policy aspcud
aspcud:
Installed: 1:1.8.0-2
Candidate: 1:1.8.0-2
so that was good. I could not install 2.9.0 with ‘opam', but I tried 2.7.0, as
per the skeleton’s readme file, and that installs on 14.04.
When I ran
mc@xenpro7:~/mirage-skeleton/console$ mirage configure —xen
next, it downgraded mirage. So I reinstalled mirage.2.7.0 but then ran eval
`opam config env`. (I am learning.) Doing it this way, configure works as
desired, ‘make' builds the guest image and the guest image runs perfectly. So
this thread has a recipe for getting the current skeleton to build Hello World
on Ubuntu 14.04.
Sincerely,
John
