# Arch Linux - Switch to LTS Kernel

There are two starting points. If your boot partition isn't very large, you'll get errors when installing the linux-lts package. Example:

```bash
zstd: error 25 : Write error : No space left on device (cannot write compressed block)  
bsdtar: Write error 
bsdtar: Write error 
==> ERROR: Image generation FAILED: sort reported an error 
error: command failed to execute correctly
```

So I just deleted all of the .img files in /boot

```bash
sudo rm /boot/*.img
```

Now install the LTS kernel. If you reboot before installing the new one, your system will not boot.

```bash
sudo pacman -Syu linux-lts linux-lts-headers
```

If using VirtualBox, you need to swap its kernel modules to match the new LTS kernel before you can remove the Linux package.

```bash
sudo pacman -S virtualbox-host-dkms
```

Allow the replacement.

`virtualbox-host-dkms and virtualbox-host-modules-arch are in conflict. Remove virtualbox-host-modules-arch? [y/N] y`

Now remove the linux and linux headers packages

```bash
sudo pacman -R linux linux-headers
```

Finally, update your bootloader.

```bash
sudo grub-mkconfig -o /boot/grub/grub.cfg
```
