Ubuntu apt warning - http://repo.mysql.com/apt/ubuntu

[Paul Danford]

Hi,

I'm getting the following security warning when running the following on Ubuntu:

sudo apt-get update

This is the warning displayed:

http://repo.mysql.com/apt/ubuntu/dists/xenial/InRelease: Signature by key A4A9406876FCBD3C456770C88C718D3B5072E1F5 uses weak digest algorithm (SHA1)

Any idea as to the cause and how to resolve?

Cheers,
Paul
