Hi Hans
I was going to install Pd-extended from here: http://autobuild.puredata.info/auto-build/2011-09-16/Pd-0.43.1-extended-2011...
on a Ubuntu 11.04 machine and I got this:
Unpacking pd-extended (from Pd-0.43.1-extended-20110916-ubuntu-natty-i386.deb) ... dpkg: error processing Pd-0.43.1-extended-20110916-ubuntu-natty-i386.deb (--install): trying to overwrite '/usr/bin/pd', which is also in package puredata 0.42.6-2 dpkg-deb (subprocess): data: internal gzip write error: Broken pipe dpkg-deb (subprocess): failed in write on buffer copy for failed to write to pipe in copy: Broken pipe dpkg-deb: error: subprocess <decompress> returned error exit status 2 Errors were encountered while processing: Pd-0.43.1-extended-20110916-ubuntu-natty-i386.deb
It seems, that 'pd-extended' is conflicting with 'puredata' without mentioning 'puredata' in the 'Conflicts:' section. I think either it should be mentioned there or - what I think would be the better solution, if possible at all - it should not try to overwrite /usr/bin/pd.
I don't know the current state of Pd-extended-0.43, probably it's still very much work-in-progress. I thought I mention this anyway.
