Also having the same issue on 64-bit arch. I had already cleaned my package cache so following the instructions in comment #15 reported non- existent package but downloading it anew as suggested in comment #20 seems to have fixed it. Thanks @pauljwells.
I've just updated apt and the "1.20.1-0ubuntu4" packages claiming to have fixed the issue are still not available. I'll come back and confirm the fix when they roll out. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/767498 Title: package apport 1.20.1-0ubuntu3 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
