Now that elementary OS Loki Update 1 (0.4.1) has been released, how can I upgrade to it without reinstalling?
Step 1. Update
- Open up
- Navigate to the
- Install all available updates
- Reboot if required
System Settings > About section should look like the following image. Note that it states "elementary OS 0.4.1 Loki", not 0.4.
Step 2. Upgrade Kernel [Optional]
While your system now runs the latest version of elementary OS, it may not be running the latest kernel underneath. If you experience no problems with your hardware, this upgrade may only create minor performance imporvements. However, if your brightness or wireless was unsupported, this may fix some of your problems.
This is dangerous. You should create a backup before proceeding.
sudo apt-get install --install-recommends \ linux-generic-hwe-16.04 \ xserver-xorg-hwe-16.04 \ xserver-xorg-core-hwe-16.04 \ xserver-xorg-input-all-hwe-16.04 \ xserver-xorg-input-evdev-hwe-16.04 \ xserver-xorg-input-libinput-hwe-16.04 \ xserver-xorg-input-synaptics-hwe-16.04 \ xserver-xorg-input-wacom-hwe-16.04
Once this is complete and you have rebooted, you should see
Linux 4.8.* in the elementary section of the
About settings panel, instead of 4.4.*
