Signature by key ACCAF35C uses weak digest algorithm (SHA1)

Bugs and issues Linux
#1

Recently I received the follow message when I did an update:

Signature by key AEEB94E9C5A3B54ECFA4A66AA684470CACCAF35C uses weak digest algorithm (SHA1)

I tried these instructions in order to fix the repository, but without success:

$ sudo apt-key remove ACCAF35C
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ACCAF35C
$ sudo apt-get update

Do you have any idea how to fix it?

Got exactly the same message on Linux Mint 18.1 as of today - after the latest version 1.3.15.36150 got installed!

I’m getting the same error message, Insync is not initiating right after installing upgrades today.

I’m on Ubuntu 17.04, I have insync 1.3.14.36131 installed. Ran apt update today, and getting:

Err:5 http://apt.insynchq.com/ubuntu zesty InRelease
  The following signatures were invalid: AEEB94E9C5A3B54ECFA4A66AA684470CACCAF35C

Tried to remove the key and re-add it, but have the same result. My apt source file has:

deb http://apt.insynchq.com/ubuntu zesty non-free contrib
