In this article, we will be addressing the issue “system does not fully support snapd: cannot mount squashfs image” that you may encounter in Ubuntu 20.04. We will provide a step-by-step guide to help you navigate this problem.
To fix the "system does not fully support snapd: cannot mount squashfs image" issue in Ubuntu 20.04, you can either bypass snapd and directly install certbot, or install a different kernel that supports all the necessary features.
Understanding the Issue
The error message “system does not fully support snapd: cannot mount squashfs image” usually arises when certain Linux kernel features are not available on your system. This may be the case if you’re running a containerized server under OpenVZ. The error essentially indicates that your system is unable to mount squashfs images using snapd.
Solution 1: Bypass Snapd and Install Certbot Directly
One of the simplest solutions to this issue is to bypass snapd and directly install certbot. You can do this by using the following command:
sudo apt install certbotHere, sudo allows you to run the command as a superuser, apt is the package handling utility in Ubuntu, install is the command to install a new package, and certbot is the package you want to install.
This command will install certbot directly without the need for snapd. However, it’s important to note that snapd provides additional benefits and functionalities. So, if you specifically require snapd, you may need to consider alternative solutions.
Solution 2: Install a Different Kernel
If you specifically need to use snapd, you may need to install a different kernel that supports all the necessary features. This is a more complex solution and should only be attempted if you are comfortable with modifying your system at a low level.
You can check your current kernel version with the following command:
uname -rThis command will display the current kernel version. uname is a command that prints system information, and -r is a flag that specifies you want to see the kernel version.
To install a new kernel, you will first need to update your package lists for upgrades and new package installations:
sudo apt updateAfter this, you can install a new kernel version. You can find the available versions on the Ubuntu website. Once you have chosen a version, you can install it with the following command (replace x.x.x-xx with your chosen version):
sudo apt install linux-image-x.x.x-xx-genericAfter the installation is complete, you will need to reboot your system for the changes to take effect:
sudo rebootConclusion
The error message “system does not fully support snapd: cannot mount squashfs image” can be a frustrating issue to encounter, but it is not insurmountable. By either bypassing snapd or installing a different kernel, you can overcome this problem.
Remember, if you’re unsure about anything, it’s always best to ask for help. The Ubuntu community is a great resource, and there are many experienced users who can provide assistance. You can also refer to the official Ubuntu documentation for more information.
