Lately I receive these errors. I am running Ubuntu 16.

Can you try if this version works for you?

That worked. I had to first remove the key. Re-add it then performed an apt-get upgrade.

Ubuntu 18.04.5 LTS
Insync 3.2.6.40863

I have the same problem!
How to remove the key?

Hi! Please run
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys ACCAF35C :slight_smile:
