Problems installing MongoDB on Ubuntu 20.04

Following the documentation for Mongo 4.4 on Ubuntu, I get the key, add the repository, then get the following error when running atp-get update:

Err:6 focal/mongodb-org/4.4 Release
Could not handshake: The TLS connection was non-properly terminated. [IP: 9480]
Reading package lists... Done
E: The repository ' focal/mongodb-org/4.4 Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

If I try to curl to the page I get the following:

<head><title>404 Not Found</title></head>
<h1>404 Not Found</h1>
<li>Code: NoSuchKey</li>
<li>Message: The specified key does not exist.</li>
<li>Key: apt/ubuntufocal/mongodb-org/4.4multiverse</li>
<li>RequestId: C5JWFBGFTN5X4B10</li>
<li>HostId: RHZGG+Mt6t/Gmo25ZCTy1L5+8NaZiz+NqCuDxYYd8iTyiKjMuUvUKU3Zm+gKbbJd5H5aMzal+fQ=</li>

Am I looking at a key issue or is something not right with the repo?

Please have a look on below link and follow steps for ubuntu 20

I have been following every guide I can find.

Hi @jon_rawlins,
