According to a post by AZorin, if you update once from the Software Updater application, it should resolve this.

"apt update" return "Certificate verification failed" for https://packages.zorinos.com/apps

Hi @meo! There have recently been updates to some of the packages that handle web security verification such as ca-certificates and others that handle SSL and TLS in order to support the updated security certificates in some of the repositories. If you see this error message, you might not have installed these updated packages. In order to resolve this issue, please install the latest updates from the Software Updater.

Oooooo, that sounds magical, oh how exciting!

Gosh, I love it when a plan comes together, even in the oddest of ways...

Have this issue. Tried the suggested steps in the other thread. I still get the error "Release' no longer has a Release file." on the archive servers. All the other servers are updating. I'll probably just wait for an update that fixes this. I haven't found any other steps to try.

Please try

sudo apt install ca-certificates

sudo apt update && sudo apt upgrade

Thanks for this, it did the trick. I had just installed Zorin OS Lite 15.3 and tried to check for updates which failed.
