@dagood Thanks for the response. I am following the exact instructions as per:
https://docs.microsoft.com/en-ie/dotnet/core/install/linux-package-manager-centos7

Specifically:

#> rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm
#> yum install dotnet-sdk-3.1

The exact output of the above commands are:

#> rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm

@thecosmicfrog thanks for the extra detail, copied it out to a new issue because the earlier one was resolved, and this doesn't repro for me on CentOS 7. Taking a look vs. the output of my install commands to see if I can spot any differences.

It looks like the mirror you're being routed to is broken! I get a different IP address 13.91.48.226 vs. your 13.74.252.37:

For now, as a workaround, you could use the IP I get routed to to acquire and install the correct RPM manually. I don't know how (or if it's possible) to specify the mirror to use for our repo.

We're filing a ticket with the team responsible for these package repositories to get them to investigate the apparent broken mirror.

The repo admins ran a manual copy between the mirrors to fix this, and the wget via the mirror's IP works for me. This should make the install command work, but please let us know if you still hit issues @thecosmicfrog.

Sweet, thanks for confirming (and again for the original report). Unfortunate that this is something we apparently need to be concerned about. 😕 I'm going to double-check that this is something we're tracking along with the overall reliability issues with the service. (#4167)
