break-lock doesn't do the trick.

It would be helpful if I could see the full output, but I would suggest trying `bzr break-lock :push` and if that doesn't work, then please post all the output from that command.

Is this the command you mean "bzr break-lock push:~peter-stockholm/barcodesforpython/main" ?
In any case, what I pasted above is all I get as output even with -v, don't know how to get more output from bzr.

Peter your branch appears to be empty. You could try deleting it using the web interface and pushing again.

Peter, to answer your other question, the use of ":push" in place of a location tells bzr to substitute the push location. You can also use :parent, :submit, :public, :this, and :bound as appropriate. These aliases were introduced in bzr 1.6.

I created a new branch because I wanted to get the sources up, if there's a way to delete the locked branch that is good enough for me. I hope that is ok.

bzr push nosmart+bzr+ssh://bazaar.launchpad.net/....... will do.
