Error while trying to install google chrome

Hi,

When I try to install Google chrome I get the following message

failed to install file: [PK_TMP_DIR|dir:///var/tmp/TmpDir.R7iwcu] Repository already exists.

Before installing chrome I tried to install Google Earth but because the installation process was taking a long time I canceled it. Is this the reason behind the complication ?

How to solve this ?

the problem should disappear if you remove that directory.
