#linux snap

This command utilizes Pacman, the package manager for Arch Linux, to download and install AppArmor.

Step 2: Verify and Install Snapd

Next, we need to check if Snapd is already installed on your system. You can do this by executing:

pacman -Qs snapd

If Snapd is not installed, you can easily install it using an AUR helper like yay. Run the following command:

yay -S snapd

Step 3: Auto-Launch AppArmor on Boot

To ensure that AppArmor launches on boot, you need to modify your boot configuration. First, check where your boot entries are located:

ls /boot/loader/entries/

Depending on your system configuration, your path might be /efi/loader/entries/. Look for the file that corresponds to your Arch Linux installation, typically named arch.conf. Open it with a text editor:

sudo nano /boot/loader/entries/arch.conf

In this file, locate the existing options line. You will want to add the following parameters to the end of this line:

lsm=landlock,lockdown,yama,integrity,apparmor,bpf

Your modified entry should look something like this:

title Arch Linux linux /vmlinuz-linux initrd /initramfs-linux.img options root=UUID=xxxx-xxxx rw quiet lsm=landlock,lockdown,yama,integrity,apparmor,bpf

Step 4: Reboot and Verify

Unlike GRUB, you do not need to run a "config update" command since systemd-boot reads these files directly every time you start your system. Now, reboot your machine:

sudo reboot

Once your system has restarted, check the status of AppArmor with the following command:

aa-enabled

If it returns "Yes," then the AppArmor Shield is active and running successfully.

Step 5: Trigger the Snapd Service

Now that your kernel is aware of AppArmor, it’s time to get Snapd running smoothly. Start by enabling the AppArmor engine:

sudo systemctl enable --now apparmor.service

Next, you'll want to force Snapd to recognize the new kernel state:

sudo systemctl restart snapd.service

Finally, enable and start the Snapd AppArmor service:

sudo systemctl enable --now snapd.apparmor.service
