Andrew, you did it wrong. apt download libffi8 libffi8:i386 for d in libffi8*.deb; do dpkg-deb -x $d $d.dir; dpkg-deb -e $d $d.dir/DEBIAN; sed -i 's/Breaks: libffi8ubuntu1/Breaks: libffi8ubuntu1 (<= 3.4~20200819gead65ca871-0ubuntu5)/' $d/DEBIAN/control; dpkg-deb -b $d.dir $d; done sudo dpkg -i libffi8*.deb
And after the installation, do not update libffi8 again until a new version out. sudo apt-mark hold libffi8 libffi8:i386 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1943312 Title: dependency problems of version 3.4.2-1ubuntu3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libffi/+bug/1943312/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
