The bug was fixed by unistalling the package hal, hal-info and libmbca0 (this file was reported by dpkg) and then reinstalling them The process went like this: sudo dpkg -r hal hal-info and if any other file is showing error add that file also, then sudo aptitude reinstall
This has fixed the problem now run sudo dpkg --configure -a Thanks all Rajinder Sandhu -- dpkg: ../../src/packages.c:221: process_queue: Assertion `dependtry <= 4' failed https://bugs.launchpad.net/bugs/305892 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
