Fix swap

Installing kubernetes needs swap should be disabled. Check if swap is enabled and then disable if swap is enabled.

Disable swap

sudo swapoff -a

Remove / comment out respective swap entry from fstab file

sudo nano /etc/fstab

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
