Add dist-tag error with how-to-npm


I’m working on the how-to-npm tutorial and on the step Dist Tag I can’t seem to get the dist tag added properly.

I have tried countless different variations of the solution recommended on these forums
npm dist-tag add @{username}/{package name}@{version number} {tag}

as well as many variations of the supplied documentation

npm dist-tag add @linclark/pkg@1.0.1 beta
npm dist-tag add linclark@1.0.1 beta
npm dist-tag add pkg@1.0.1 beta
npm dist-tag add @username/linclark@1.1.0 [“beta”]
npm dist-tag add @username /linclark/pkg@1.0.1 [beta]

and no matter if the command succeeds and I get
+[beta]: @linclark/pkg@1.0.1
or the command results in one of the following errors

npm ERR! code E404
npm ERR! 404 missing : -/package/@username%2flinclark/dist-tags

npm ERR! A complete log of this run can be found in:
npm ERR! /home/ubuntu/.npm/_logs/2017-08-16T13_33_06_978Z-debug.log

when I check to see if it’s added using npm dist-tag ls there’s only one dist-tag and the how-to-npm verify check will fail

Any help completing this would be greatly appreciated.
