Status changed to 'Confirmed' because the bug affects multiple users.

[Li Zhou (deatherving)]

I got the same problem. WHen I run apt-get update, I receive the warning:

W: Invalid 'Date' entry in Release file /var/lib/apt/lists/partial/_var_cuda-repo-8-0-local_Release
W: Invalid 'Date' entry in Release file /var/lib/apt/lists/developer.download.nvidia.com_compute_cuda_repos_ubuntu1604_x86%5f64_Release

Any solution?

[David Kalnischkies (donkult)]

The solution is to tell the owners of the respective repositories to fix their Release file(s). The Date (and Valid-Until) field MUST be in UTC (aka GMT, Z, +0000). Earlier apt versions accepted other timezones silently, but parsed it as UTC anyhow which could cause all kinds of fun. Now a /warning/ is generated – a user can work with the repository as before. As the content of that field is only of use for applications and apt isn't a fullblown calendar-application we decided to not implement all the craziness which is time.

All hints for creating repositories which apt (and other clients and servers) can work with: https://wiki.debian.org/RepositoryFormat

So, as this isn't a bug: Closing as invalid.

[Bump (bump55)]

Ok who is the developer of that repository?

[Li Zhou (deatherving)]

Thanks David. I will post the related info to nvidia.
