Unable to Remove Kernel Package - No Space Left on Device

[Leapveera]

I am experiencing an issue with removing a kernel package on my Proxmox server, and I could use some assistance in resolving the issue. Here are the details:

System Information:

• Proxmox Version: pve-manager/7.4-17/513c62be (running kernel: 5.15.108-1-pve)
• Operating System: Prxmox
• Installation Method: ISO

Whenever I tried to run the apt upgrade, or apt autremove, it shows below error
Reading package lists... Done Building dependency tree... Done Reading state information... Done The following packages will be REMOVED: linux-image-5.10.0-24-amd64 0 upgraded, 0 newly installed, 1 to remove and 6 not upgraded. 6 not fully installed or removed.

This looks like you have no space left on your EFI disk. Can you mount it manually and check?
