4.0 Upgrade Problem


I am having problems upgrading to 4.0 (Ubuntu 16.04). When I do a sudo apt update I get this:

$ sudo apt update
Get:1 file:/var/cuda-repo-8-0-local-ga2 InRelease
Ign:1 file:/var/cuda-repo-8-0-local-ga2 InRelease
Get:2 file:/var/cuda-repo-8-0-local-ga2 Release [574 B]
Get:2 file:/var/cuda-repo-8-0-local-ga2 Release [574 B]

Ign:13 https://releases.mapd.com/ce/apt stable InRelease
Get:14 https://releases.mapd.com/ce/apt stable Release [8,604 B]
Err:15 https://releases.mapd.com/ce/apt stable Release.gpg
404 Not Found
Reading package lists… Done
E: The repository ‘https://releases.mapd.com/ce/apt stable Release’ is no longer signed.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.


Thanks for reporting, I pinged an internal engineer. It’s still pretty early on the West Coast, so maybe check back in an hour or two and hopefully it will be resolved.


@HokieKev, I’ve been told it’s fixed. Can you try again and let me know if you have any issues?


Yes. Works perfectly now. Thanks.
