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 Touch seeded packages, which is subscribed to click in Ubuntu. https://bugs.launchpad.net/bugs/1615757 Title: click install fails on 16.10, causing user install and autopkgtest failures Status in click package in Ubuntu: New Bug description: click crashed with: click crashed with subprocess.CalledProcessError in run(): Command '['dpkg', '--force-not-root', '--force-bad-path', '--force- architecture', '--instdir', '/opt/click.ubuntu.com/com.ubuntu.filemanager/0.4.525', '--admindir', '/opt/click.ubuntu.com/com.ubuntu.filemanager/0.4.525/.click', '--path-exclude', '*/.click/*', '--log', '/opt/click.ubuntu.com/.click/log', '--no-triggers', '--install', '/home/emanuele/Scaricati/com.ubuntu.filemanager_0.4.525_multi.click']' returned non-zero exit status 1 ProblemType: Crash DistroRelease: Ubuntu 16.10 Package: click 0.4.44+16.10.20160811.1-0ubuntu1 ProcVersionSignature: Ubuntu 4.4.0-9134.53-generic 4.4.15 Uname: Linux 4.4.0-9134-generic x86_64 ApportVersion: 2.20.3-0ubuntu7 Architecture: amd64 Date: Mon Aug 22 11:16:02 2016 ExecutablePath: /usr/bin/click InstallationDate: Installed on 2016-08-21 (1 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) InterpreterPath: /usr/bin/python3.5 ProcCmdline: /usr/bin/python3 /usr/bin/click install --user emanuele /home/emanuele/Scaricati/com.ubuntu.filemanager_0.4.525_multi.click ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=it_IT.UTF-8 LANGUAGE=it SHELL=/bin/bash PythonArgs: ['/usr/bin/click', 'install', '--user', 'emanuele', '/home/emanuele/Scaricati/com.ubuntu.filemanager_0.4.525_multi.click'] SourcePackage: click Title: click crashed with subprocess.CalledProcessError in run(): Command '['dpkg', '--force-not-root', '--force-bad-path', '--force-architecture', '--instdir', '/opt/click.ubuntu.com/com.ubuntu.filemanager/0.4.525', '--admindir', '/opt/click.ubuntu.com/com.ubuntu.filemanager/0.4.525/.click', '--path-exclude', '*/.click/*', '--log', '/opt/click.ubuntu.com/.click/log', '--no-triggers', '--install', '/home/emanuele/Scaricati/com.ubuntu.filemanager_0.4.525_multi.click']' returned non-zero exit status 1 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/click/+bug/1615757/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
