Sylvain, this package is small so your diff shouldn't be a problem but when using diff directly its a good practice that all +++ lines, which are like metadata about where to apply the patch, contain the same name as the originals with a relative path 1 level higher than the package tree, specially when the diff patchesmore than one file.
So it gets like this: --- iso-scan.orig/debian/iso-scan.postinst +++ iso-scan/debian/iso-scan.postinst And the dev, just needs to cd $PACKAGE; patch -p1 < patchfile instead of patch originalfile patchfile I'm not sure why I had doubts in #1 but this bug does affect debian too and its just that line (I thought there were 2...). I'll open a bug upstream. Optionally, If you want, you can fix it directly by purposing a merge to the branch lp:~ubuntu-core-dev/iso-scan/ubuntu using the procedure mentioned in https://wiki.ubuntu.com/Bugs/HowToFix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/838720 Title: Crash on folder name with spaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iso-scan/+bug/838720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
