Linux install failed: nuget reports signature expiration and self-signed certificate

[smr99]

I got to Step 2 of the install instructions (using Debian linux, with .NET 5) and this is the result. Is it true that a signature needs to be re-done? Or is it an issue on my side? I'm using Debian-provided .NET packages.

$ dotnet tool install --framework net5.0 -g SharpBrick.PoweredUp.Cli [ .... welcome text elided .... ]

error NU3028: Package 'SharpBrick.PoweredUp.Cli 3.4.0' from source 'https://api.nuget.org/v3/index.json': The repository primary signature's timestamp found a chain building issue: UntrustedRoot: self signed certificate in certificate chain error NU3037: Package 'SharpBrick.PoweredUp.Cli 3.4.0' from source 'https://api.nuget.org/v3/index.json': The repository primary signature validity period has expired. The tool package could not be restored. Tool 'sharpbrick.poweredup.cli' failed to install. This failure may have been caused by:

• You are attempting to install a preview release and did not use the --version option to specify the version.
• A package by this name was found, but it was not a .NET tool.
• The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
• You mistyped the name of the tool.

I tested it on my slightly outdated pi ... it works there.

I do not sign my packages. So as a package author i am not involved in any signature work in the processing chain. Considering both messages, have you considered checking your system clock? my gut tells me, that there is something wrong there ;)

Thanks for that. I agree it is likely my system, then. I tried a different tool (nrconfig.tool) and I got the same kind of errors.

Always glad to help. When you found out, send me a note. I am curious.
