When I ran apt-get, the system said that dpkg is broken, use sudo dpkg --configure -a to recover, but when I ran sudo dpkg --configure -a, it showed the following error message:

dpkg: error: liboil0.3:amd64 0.3.16-1ubuntu2 (Multi-Arch: no) is not co-installable with liboil0.3 which has multiple installed instances

How do I fix this? Please help.

What was the reason behind this error means,you are trying to install 64 bit version of liboil0.3,but your system has already installed a 32-bit version of liboil0.3.Run the below command in terminal to fix this problem.

sudo dpkg -r liboil0.3:i386

  • open `synaptic package manager`,search for liboil0.3 and uninstall it.Then run `apt-get` command. – Avinash Raj Nov 12 '13 at 14:54
  • above is the output message `sudo dpkg -r liboil0.3:i386` it steady show the message `dpkg: error: liboil0.3:amd64 0.3.16-1ubuntu2 (Multi-Arch: no) is not co-installable with liboil0.3 which has multiple installed instances ` `synaptic package manager` not work properly, i can't remove any software. I think the error is the same. – Yu Jiaao Nov 13 '13 at 00:05
  • when I open synaptic package manager, it says `E: dpkg 被中断，您必须手工运行 dpkg --configure -a 解决此问题。` `E: _cache->open() failed, please report.` when I manually run the command `dpkg --configure -a` it shows the message dpkg: error: liboil0.3:amd64 0.3.16-1ubuntu2 (Multi-Arch: no) is not co-installable with liboil0.3 which has multiple installed instances – Yu Jiaao Nov 13 '13 at 00:53
