Hi,
I’m trying to install latest version of docker on a couple of Ubuntu 16.04 machines but the package can’t be verified
root@xxx:~/downloaded# apt-get install docker-ce

The following package was automatically installed and is no longer required:

Use ‘sudo apt autoremove’ to remove it.
The following additional packages will be installed:
aufs-tools cgroupfs-mount libltdl7
Suggested packages:
mountall
The following NEW packages will be installed:
aufs-tools cgroupfs-mount docker-ce libltdl7
0 upgraded, 4 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B/19.4 MB of archives.
After this operation, 89.4 MB of additional disk space will be used.

I tried to verify by manually download the file
