@ Leo, My experience is that cloning is cloning is cloning, whereever it is done, as long as the cloning operation is done correctly, and it is not too difficult. And the test of the files at boot indicates no error, so I am rather confident.
Anyway, I can do the cloning elsewhere, in another computer, and with another operating system and with another tool. Please suggest what I should try, and I will try it, version of Lubuntu, Windows, Rufus in dd- mode or whatever (but I have no access to a Mac computer/operating system). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886148 Title: failure to boot groovy daily To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1886148/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
