Has anyone faced similar issue? How do I fix it?

Hi rangaresearch,

I have no idea about this, may other developer help to provide suggestions.

I tried updating the packages and rebooting. It didnt work.
I am also unable to run emulators like retroarch and ppsspp which I installed through the terminal. They crash on starting. Once the error message mentioned obsolete packages…

Really need help here…

Here is the log for the issue. After the authentication is success, getting cant initialize nvrm channel
