install & apdate linux mint

[tantal]

Hello!

I installed Linux Cinnamon for a few minutes. After installation, I downloaded the video card driver through the driver manager. Everything worked perfectly.

After installing the service packs, everything went wrong. The video card driver crashed. The service pack manager returned an update error and refused to start. After the next system startup, Linux was full of errors and wouldn't start at all.

Tell me how I can update the video packages and drivers without affecting the OS.

What errors did I see?
sudo apt-get update doesn't work. I get an error. I searched the internet, fixed it, and they say it's a long-standing problem.

Code: [Highlight]
error while installing package: subprocess from package initramfs-tools installed post-installation script returned error code 1
This error persists after installing updates. The video drivers aren't installing. I googled it, and it says the hard drive is full, but that's not the case. My HDD is clean.
