Unable to update Home Assistant Operating System

I am stuck at the OS version 5.13. I am able to downgrade using SSH on terminal but upgrading to any version like 6.0, 6.6 or above does not work. I saw few people has success in going to v 6.6 and then 7.0 but it doesn’t work for me.
I am using Linux on virtualbox.

That’s an issue with the kernel your host is using, no?
