Cannot install ccache

[Dmitry]

According to https://wiki.ubuntu.com/PbuilderHowto#Speeding_up_the_package_installation one may use ccache to speed up the compilation. However,

# pbuilder --create --override-config --components "main restricted universe multiverse" --extrapackages "ccache"

fails with the error

E: Held packages were changed and -y was used without --allow-change-held-packages.

The full build log is attached.

"update" action fails with the same error too.

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.
