Comment 3 for bug 1243615

This is still a problem on Trusty 14.04 (synaptic 0.81.1ubuntu1). Because I use a local apt-cacher-ng service, I have this config file:

    $ cat /etc/apt/apt.conf.d/02nocache
    Dir::Cache::srcpkgcache "";
    Dir::Cache::pkgcache "";

Upon starting, Synaptic displays a dialog box containing:

    E: Could not open file - open (2: No such file or directory)
    E: _cache->open() failed, please report.

Closing the box also closes Synaptic.
