Update error from ipfs v0.12 -> v0.14 using ipfs-update

I get an error when executing the command line : “ipfs-update install latest”
ERROR: install failed: could not move old binary: remove /usr/local/bin/ipfs: permission denied
System: ubuntu server
current ipfs version : 0.12
ipfs-update version: 0.18

Try sudo ipfs-update install latest
