There was an old Ubuntu 14.04 linode.com instance which I attempted to upgrade to 18.04. Some Dependencies where somehow not upgraded anyway.
So I attempted to install corresponding deb file from Ubuntu server (as it was not in repo)
The following packages have unmet dependencies:
dpkg : Breaks: libdpkg-perl (< 1.18.11) but 1.18.4ubuntu1 is to be installed
Breaks: libdpkg-perl:i386 (< 1.18.11)
libc-bin : Depends: libc6 (< 2.25) but 2.27-3ubuntu1.2 is to be installed
locales : Depends: libc-bin (> 2.27)
I accidentally installed wrong version of libc6 which result to damage the instance.
root@myself:~# dpkg -i libc6_2.27-3ubuntu1_amd64.deb
dpkg: warning: downgrading libc6:amd64 from 2.31-0ubuntu9.2 to 2.27-3ubuntu1

---------------------------------------------
So attempting a rescue mode is the only option. It seems libcrypt dependency is causing the error.
How to solve this in rescue mode. Any advice please.
