I'm having trouble reinstalling grub through chroot, I get the following error whenever I try to reinstall it.
error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory
Little bit of a backstory:
Recently while trying to convert my disk partition from MBR to GPT, I bricked my Ubuntu Installation. Once i restarted after using the following command sgdisk -g /dev/sda I was unable to boot into Ubuntu!
My Main aim was to convert the MBR LVM partition to GPT so as to install Windows 10. I was under the impression that I had to change it into GPT to be able to install windows 10 but later found that simply resizing the partition using KDE Partition Manager or any other tool capable of LVM operations and then formatting the partition to NTFS ought to make the environment ready for installation of Windows 10.
The Problem Now:
While I've managed to get windows 10 running and as I type from it now, I'm in a bit of a rut, I love using Ubuntu Linux and I want a dual boot setup, Windows being used for Multimedia stuff & Games whereas Ubuntu Linux being the daily Operating System!
I came across an software called boot repair disk by yannubuntu on sourceforge, I booted it up on a usb stick and then ran the boot repair software, it asked me to execute the following command sudo chroot "/mnt/boot-sav/mapper/vgubuntu-root" apt purge --allow-remove-essential -y grub*-common shim-signed so as to reinstall and configure grub on the Ubuntu LVM partition using chroot.
When I execute this command, I always get this library error /bin/bash: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory dpkg: error processing package grub-pc (--remove): even though the libraries are installed in the boot repair disk as I found out while trying to install it using apt and I assume it is preinstalled in Ubuntu as well as the library is already present in the boot repair disk and it is based on Ubuntu.
Here's the full terminal view of my issue, the command executed and the aforementioned errors can be seen here.
Command:
sudo chroot "/mnt/boot-sav/mapper/vgubuntu-root" apt purge --allow-remove-essential -y grub*-common shim-signed
Output:
lubuntu@lubuntu:~$ sudo chroot "/mnt/boot-sav/mapper/vgubuntu-root" apt purge --allow-remove-essential -y grub*-common shim-signed

Note:
Some things that I've already tried:
- Tried reinstalling grub on the bricked Ubuntu using chroot from a full fat Ubuntu 18.04 on a USB stick, the same library error persists
