Ok I have it. Python is the problem. All programms, witch want a one user, have a problem. Python logt the passwd. If I kill Phyton and remove se locks i can normal install an deinstall all programms.
For examble: # /usr/sbin/useradd -d /home/usbmux -g plugdev -s /bin/false -u 119 usbmux useradd: cannot lock /etc/passwd; try again later. You can see that Pyhton logt the passwd: #lsof | grep passwd python 2041 user123 10u REG 8,5 1908 4661 /etc/passwd And with this workaround i can install all programms # killall python # rm /etc/passwd.lock # rm /etc/shadow.lock # dpkg --configure usbmuxd -- Error with some packages upgrade https://bugs.launchpad.net/bugs/546492 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
