Seth - you are a star - thank you so much. I would never have guessed that an AV system (Sophos) could, without reporting any virus detection or other issue, prevent installation on one system whilst the same version does not prevent it on another. Suffice to say that disabling on-access scanning for the duration of installation fixed the problem.
Very weird indeed. So, as a matter of protocol, do I close this as 'not a bug' or is that up to someone from ubuntu? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1696132 Title: package linux-headers-4.10.0-22-generic 4.10.0-22.24 failed to install/upgrade: unable to open '/usr/src/linux- headers-4.10.0-22-generic/include/config/dw/dmac/core.h.dpkg-new': Operation not permitted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1696132/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
