Java installation error using apt-cacher

I'm getting this output when I trey to update/install oracle-java7 or from webupd8 ppa:

Oracle JDK 7 is NOT installed.
dpkg: error processing package oracle-java7-installer (--configure):

My /etc/apt-cacher.conf

#package_files_regexp = (?:^[-+.a-z0-9]+_(?:\d:)?[-+.~a-zA-Z0-9]+(?:_?[-a-z0-9]+\.(?:u|d)?    deb|\.dsc|\.tar(?:\.gz|\.bz2|\.xz)|\.diff\.gz)|\.rpm|index\.db-.+\.gz|\.jigdo|\.template)$

#pdiff_files_regexp = ^2\d{3}-\d{2}-\d{2}-\d{4}\.\d{2}\.gz$

#index_files_regexp = ^(?:Index(?:\.bz2)?|(?:Sources|Packages|release)(?:\.gz|\.bz2)?|Release(?:\.gpg)?|InRelease|Contents-(?:[a-z]+-)?[a-zA-Z0-9]+\.gz|(?:srclist|pkglist)\.[a-z-    ]+\.bz2|Translation-[a-z]{2,3}(?:_[A-Z]{2}(?:\.[a-zA-Z0-9-$

I think apt-cacher doesn't like the format of the file jdk-7u72-linux-x64.tar.gz but I am not able to change the configuration to allow it.

Solution 1:

Ok, finally I've found a solution in this post.

Adding

Acquire::http::Proxy { download.oracle.com DIRECT; }; 

in the proxy configuration /etc/apt/apt.conf.d/01proxy.
