Reinstall doesn't help. The problematic line is in postinst:
[ -x /bin/systemctl ] && [ -d /run/systemd/system ] && systemctl enable pcscd.socket On my Trusty system, even calling this command from commandline (with sudo at systemctl) fails with the same error. Using strace I found out that on this system it looks for the socket file in /lib/systemd/upstart/pcscd.socket, but the package only installs /lib/systemd/system/pcscd.socket. Manually copying this file to the correct directory fixes the issue (symlink is not enough since systemd doesn't follow them). It's probably caused by this systemd change from December 2016: https://bugs.launchpad.net/ubuntu/trusty/+source/systemd/+bug/1616422/comments/21 . That would explain why I succeeded installing pcscd on trusty a few years ago, but now it's broken. It could be fixed in debian/rules: override_dh_auto_configure: dh_auto_configure -- $(EXTRA_CONFIGURE_ARGS) --with-systemdsystemunitdir=/lib/systemd/system --enable-usbdropdir=/usr/lib/pcsc/drivers $(shell dpkg-buildflags --export=configure) There's a config named --with-systemdsystemunitdir which points to the ignored directory on trusty. Pointing it to /lib/systemd/upstart should IMO fix the bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1700104 Title: package pcscd 1.8.10-1ubuntu1.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcsc-lite/+bug/1700104/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
