The dpkg output from comment #6 isn't relevant, since that didn't have all the special preloading setup in place.
Adding a bit more debugging to click's preload shim (now in lp:click/devel) reveals: Error getting address of symbol 'mknod': /home/cjwatson/src/ubuntu/click/click/preload/.libs/libclickpreload.so: undefined symbol: mknod So it seems that this must be due to glibc changes, although I'm a bit baffled how that could be since xenial's libc doesn't seem to have a 'mknod' symbol either and none of the changes in the diff appear relevant. Maybe we were accidentally overloading a mknod from some other library? Not sure. Perhaps it's the overlap of several toolchain changes. Anyway, preloading __xmknod instead fixes it; it's a bit nasty, but no worse than the stuff we already do with __xstat. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1615757 Title: click install fails on 16.10, causing user install and autopkgtest failures To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/click/+bug/1615757/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
