Error when installing package

[goowikns]

Hi,

When installing your package I receive following error:

[Composer\Repository\RepositorySecurityException]
The contents of https://packagist.org/p/provider-latest%240cbfb40ab72a881d2
1b70f78286d39cd72e3b0eb8704c13e79dc49624e549973.json do not match its signa
ture. This should indicate a man-in-the-middle attack. Try running composer
again and report this if you think it is a mistake.

I can't seem to move on after this point :(

Hi @goowikns,
thanks a lot for mentioning this.
I just tested composer require jeroendesloovere/vcard and indeed.
I'm getting the same error.

Very strange...

I just released a new version 1.5.2, in the hope of fixing this. But it did not fix the problem...
Probably a packagist bug?
If somebody knows the problem, any help is appreciated.

I just tested this again and it seems to work again!
