After being unable to log in to the system (login loop), I followed the instructions in Ubuntu gets stuck in a login loop, in both the 2 most popular replies since the first one didn't work. Now after reinstalling the Nvidia graphics card using sudo apt install nvidia-430 (which was the latest version available) and then rebooting, a black screen appears saying:

[  104.636774] ipmi_si IP10001:00: There appears to be no BMC at this location

There is a cursor in the next line, but I can't type anything and it's just stuck there. Do you have any suggestions?

Your graphics card isn't compatible with the latest Nvidia 430 driver which isn't in the default repositories of any current Ubuntu release. You need to install an older graphics driver like nvidia-384 which is in the default repositories of Ubuntu 16.04. Uninstall the existing Nvidia proprietary graphics driver. To remove all the proprietary nvidia packages run the following commands.

sudo apt update
sudo apt-get remove '^nvidia'
sudo apt autoremove  
sudo reboot

Remove the PPA that you used to install the Nvidia 430 driver from your software sources (/etc/apt/sources.list) if that PPA is still there, run sudo apt update and then run the following commands from the terminal.

sudo apt install nvidia-384  
sudo reboot

Then fix the login loop by following the instructions in the answers to Ubuntu gets stuck in a login loop. If that doesn't fix the login loop, follow steps 5 and 6 in this answer.
