[Bug 1634685] Re: Cannot install ccache

[Mattia Rizzolo]

Don't do that.  I have no idea why the wiki says so (I've just fixed
it), but setting CCACHEDIR to an appropriate directory is enough to have
pbuilder do everything.

I actually believe (because you didn't copied here your pbuilderrc) that
CCACHEDIR is not even set to a non-empty value.

What you're experiencing is installing a package that pbuilder is trying to remove, it is trying to do this:
    apt-get install ccache ccache-
ending up in refusing to act, of course.

Now, if you try with pbuilder >= 0.225.1 you'd see that ccache would be
installed, but you wouldn't benefit from it because you're not
configuring a target directory.

In short, don't do anything special, just set CCACHEDIR to a directory
in pbuilderrc and drop any EXTRAPACKAGES=ccache you're setting.
