Problem with Updatemanager and apt-get upgrade

[Roger]

We have Ubuntu Precise on all machines here.

On the Dell laptop there is an issue I cannot resolve and would 
appreciate some help if possible please.

Running apt-get update && apt-get upgrade as sudo su, I get an error 
message as below.
I have run apt-get autoremove on each one, then apt-get autoclean
  Googled MaxReports - /var/crash is empty, there is no .crash file as 
mentioned in
http://languor.us/kubuntu-precise-no-apport-report-written-because-maxreports-reached-already.

Tried removing the files reported as no longer required, they will not 
remove.

Still get the MaxReports error

Thanks in advance
Roger
