Ubuntu16.04 Update and download something error

Querying system Current Kernel

Querying the system for existing kernel files

Purging Redundant kernel files

As above, Error!

A total of three error:

1. Child process Old Pre-removal script returns error status 1
2. Child process New Pre-removal script returns error status 1
3. Child process installed Post-Installation script returns error status 1

Workaround:

"Child process old Pre-removal script returned error status 1" issue:

Opened the status document, looking for the Linux kernel corresponding package, only found a linux-base package, deleted the corresponding description.

In fact, there are tens of thousands of lines of open files, it is not very good to find a string, and then you are not particularly familiar with the Linux command line.

I looked for it in the following way:

Input sudo vi/var/lib/dpkg/status

But the line number is not displayed,

Enter a colon set number and then enter to display line numbers:

Enter a slash, enter the string you want to find, and then return to the location of the string you want to find.

You can then find the line in the corresponding file.

Delete this section.
