running on a usb memory stick
Several times I have used synaptic package manager in order to remove older
kernels, and it has worked every time.
I use a procedure I found on the internet.
This time synaptic package manager would not open and I got an error message.
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.
I do not understand the message, and I do not know how to resolve it.
Thanks, if you could tell me what to do.
Remark: The error occurred after updating to the latest kernel, and I have restarted.
