Processing File Dependencies... Done
Reading Package Lists... Error!
E: There are two or more versions of the package 'grub' installed in your 
system, which is a situation
APT can't handle cleanly at the moment.
Please do one of the following:
1) Remove the older packages, leaving only one version installed; or
2) If you do want to have multiple versions of that package, add the package 
names to the RPM::AllowedDupPackages option.
 
 E: Error occured while processing grub (UsePackage2)
 E: Problem with MergeList /var/lib/rpm/packages.rpm
 E: The package lists or status file could not be parsed or opened.

есть ли способы борьбы?
