Dmitrijs?
Please file a bug against sbuild package. I'm just the messenger.
apt-get, sbuild and cross-builds are critical pieces of software for
ubuntu development. Therefore such changes should be done with minimal
amount of breakage.

There is transition required, sure it's not an library soname bump,
but it is a change in the CLI API, which is automated. And there are
no ways around it, one cannot keep apt-get blocked in debian/unstable
nor ubuntu/devel-proposed, since newest apt is always used by buildds.
Not breaking buildd / sbuild is a must.
Typically warnings should be emitted for things that will become
fatal. Rebuilds and tests should be done, e.g. codesearch.debian.net
can help to find some of the args that are passed to apt-get.
Uncordinated uploads, of changes that have a high risk of breaking
things is not good. And if apt-get is borked, it's kind of hard to
test it using usual ways (e.g. autopackage tests, reverse dependencies
tests etc.). So simple things like pbuilder / sbuild / other well
known users of apt-get CLI should be checked to not explode.

To be honest, I don't know C++, so all I read is the manpage:
apt-get [-asqdyfmubV] {update | ... | build-dep pkg ...}
-f, --fix-broken
Fix; attempt to correct a system with broken dependencies in place.
THis option, when used with install/remove, can.*
Well install/remove is not formatted as command line option. And
{upgrade|dist-upgrade|dselect-upgrade|install|remove|purge|build-dep|autoremove}
all may install/remove packages. So I naively can honestly say, sbuild
uses flags as documented by apt-get.
Note that *I* didn't use that option, sbuild uses it, and as far as I
know sbuild is the way to clean build/cross-build any debian package.
As a packager, I expect sbuild and apt to never break each other =)
Thanks for the quick fix of this bug.
Regards,
Dmitrijs.

Hey Dmitrijs, thanks for your bugreport. The -f flag means --fix-broken and is not used by apt the context of build-dep. This is why its complaining. If it breaks sbuild we can add it back, but note that it does not have any effect AFAICT (looking at the apt source). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1255806 Title: apt-get --purge -yf build-dep hello, fails with E: Command line option ‘f’ [from -yf] is not known.

This is why its complaining. If it breaks sbuild we can add it back, but note that it does not have any effect AFAICT (looking at the apt source). Above is actually a regression, which causes sbuild to fail when using AptResolver when cross-compiling. I don't know if -f actually does anything when above command is invoked. As per manpage all options apply to all sub-commands, and there are no per sub-command options/restrictions. ( [-asqdyfmubV] ) specifically, why is -f rejected yet at the same time: apt-get -oAPT::Get::Fix-Broken=true --purge -y build-dep hello is accepted? Similarly --purge had to be unbroken, see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720597 Removing options, breaks compatibility, thus shouldn't be done in a point release of such a core utility which is used in scripts.

Right, I'm sorry for the trouble and I agree that it would have been better to put the erroring into 0.10.0 instead of 0.9.13. I will add -f back so that sbuild is unbroken. Note that it has no effect on buil-dep (it does on source).
