I presume you’re here from Google, trying to find a solution on why Synology DSM is not accepting SynoCommunity‘s repo, returning a cryptic “Invalid Location” error. You’re probably running DSM 6.2.4 or older, and currently unable to upgrade to DSM due to uh, various considerations (*cough*xpenology*cough*).

Turns out it’s a SSL error, not sure if it’s related to Let’s Encrypt’s root certificate expiring a few weeks ago knocking out a sizable chunk of the web, but thanks to @publicarray over on SynoCommunity’s Discord, we have a solution

Here’s the SSH command for your convenience:

sudo mv /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-certificates.crt.bak && sudo curl -Lko /etc/ssl/certs/ca-certificates.crt https://curl.se/ca/cacert.pem

Obviously if you don’t have SSH access, you could always turn back the clock as he suggested. Either way it works!

Update Oct 22, 2021:

I’ve recently received a great tip from Freeman from Jotographer for executing the script without SSH access and NOT having to turn back the clock, here’s an excerpt from his email:

Simply “Create” > “Scheduled Task” > “User-defined script“. In the “General” tab, it doesn’t matter if the task is enable or not, but make sure the user is root. Then in the “Task Settings” tab, paste the script into the “User-defined script” field w/o sudo. Then click “OK” button to finish creating the task. Right click on the newly created task and select “Run“. After that the task can now be deleted.

Thanks Freeman, and I apologize for the broken comment system on my site, I’m still working on it :D.
