[Bug 1851925] Re: Fresh install of aptitude is broken - missing dependency?

[Axel Beckert]

I'm sorry, but I can't reproduce this issue in a clean 18.04 chroot:

aptitude is installed at version 0.8.10-6ubuntu1, too, and has a
dependency on libsigc++-2.0-0v5 (version 2.10.0-2 installed as in your
case) which contains /usr/lib/x86_64-linux-gnu/libsigc-2.0.so.0.

And aptitude works for me.

Can you run "dpkg -C libsigc++-2.0-0v5" to check if all files of that
package are there and undamaged?
