You might want to run ‘apt --fix-broken install’ to correct these.
The following packages have unmet dependencies:
nvidia-driver-535 : Depends: libnvidia-gl-535 (= 535.113.01-0lambda0.18.04.1) but it is not going to be installed
Recommends: libnvidia-compute-535:i386 (= 535.113.01-0lambda0.18.04.1)
Recommends: libnvidia-decode-535:i386 (= 535.113.01-0lambda0.18.04.1)

E: Unmet dependencies. Try ‘apt --fix-broken install’ with no packages (or specify a solution).

Hi @ayrusprofessional,

you should first do

sudo apt purge nvidia-driver-535
sudo apt auto-remove
sudo apt autoclean


to uninstall the previous driver before trying to downgrade.
