About a month ago I install Zorin 16 Core on my laptop to try it out (first time daily drive Linux, so bear with me), things are great so far. The only weird thing that only show up today is the output of "sudo apt update" suddenly error out with this:
Err:29 Index of /drivers/ focal Release
Certificate verification failed: The certificate is NOT trusted. The certificate chain uses expired certificate. Could not handshake: Error in the certificate verification. [IP: 138.68.36.163 443]
I guess it is related to the recently expired Let's Encrypt certificate? I seach around for solution but cannot find one that work. Anyone have any idea how to solve this?
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.
I already try sudo apt update and using the Software Updater, the error message still remain.
Tried running curl https://packages.zorinos.com/stable return the similar error (curl: (60) SSL certificate problem: certificate has expired).
Listing apt list ca-certificates return ca-certificates/focal-updates,focal-updates,focal-security,focal-security,now 20210119~20.04.2 all [installed].
If you're using the Terminal, please also run the sudo apt upgrade command to install the updated packages. After the installation is complete, the error shouldn't appear again.
This is the result when I tried running update and upgrade:
