That sounds a bit like fs corruption then. Can you please do cd /usr/bin; sudo strace -fvvs1024 -o /tmp/trace ln uuidd uuidd.bak
and attach /tmp/trace? I guess it really fails in link(2) with EPERM ("old name is a directory") or EACCESS ("new path directory is not writable"), but let's make double-sure. Can you please also run an fsck? ** Changed in: util-linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/1498162 Title: unable to make backup link of `./usr/sbin/uuidd' before installing new version: Operation not permitted Status in util-linux package in Ubuntu: Incomplete Bug description: Upon trying to do an apt-get upgrade I run into this error: sudo apt-get dist-upgrade Reading package lists...
