I disabled sophos by running # sudo /opt/sophos-av/bin/savdctl disable before running apt. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1673333 Title: package linux-headers-4.8.0-42 4.8.0-42.45 failed to install/upgrade: unable to open '/usr/src/linux-headers-4.8.0-42/arch/blackfin/mach- bf548/include/mach/defBF547.h.dpkg-new': Operation not permitted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1673333/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
