### Mount the partitions
```sh
sudo mkdir /mnt/ubuntu
sudo mount /mnt/ubuntu # mounts root partition
sudo mkdir -p /mnt/ubuntu/boot/efi
sudo mount /mnt/ubuntu/boot/efi # mounts efi - if applicable
# Mounts necessary directories
sudo mount --bind /dev /mnt/ubuntu/dev
sudo mount --bind /proc /mnt/ubuntu/proc
sudo mount --bind /sys /mnt/ubuntu/sys
```
### Chroot into it
```sh
sudo chroot /mnt/ubuntu
```
### (useful) Check broken packages
```sh
apt update
apt upgrade
apt install -f
dpkg --configure -a
```
### Unmount everything and reboot
```sh
sudo umount /mnt/ubuntu/sys
sudo umount /mnt/ubuntu/proc
sudo umount /mnt/ubuntu/dev
sudo umount /mnt/ubuntu/boot/efi
sudo umount /mnt/ubuntu
sudo systemctl poweroff
```
