Hello,

Just a moment ago, I installed some updates by both the update manager and the terminal (Currently I am running Zotero 5.0.96.3 on Mint 20.2). In both I got an error, which says:

Update Manager:
Failed to fetch https://github.com/retorquere/zotero-deb/releases/download/apt-get/./InRelease 401 Unauthorized [IP: 185.199.109.133 443]The repository 'https://github.com/retorquere/zotero-deb/releases/download/apt-get ./ InRelease' is no longer signed.

Terminal:
E: Failed to fetch https://github.com/retorquere/zotero-deb/releases/download/apt-get/./InRelease 401 Unauthorized [IP: 185.199.109.133 443]
E: The repository 'https://github.com/retorquere/zotero-deb/releases/download/apt-get ./ InRelease' is no longer signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

Is there something what I can do to fix this error?
