[Alex Borja]

Good day everyone!

I am new in using Linux System. I was successful in installing the Linux Lite 5.0. But when I tried installing the system, the following error occurs:

Code:

I found a solution on the NO-PUBKEY issue from here:

I was able to get the update running. However, the following error occured:

Update:

I found and applied the following command line from another forum:

Code:

sudo mv /etc/dpkg/dpkg.cfg.d/multiarch /home/$SUDO_USER

I am not sure if it is the right fix, but I was able to install the updates and rebooted the system.

Any comments/suggestions is much appreciated.
