Hey, thanks for the report. The IP 104.18.16.128 is Cloudflare, so a 403 can happen for a few different reasons. A couple questions to narrow it down:
Are you using a VPN or a corporate network or proxy?
What region are you in?
Did this APT repo work fine before?
As a temporary workaround, you can download the .deb directly from the downloads page and install it with sudo dpkg -i.
I’ll pass this to the team. We know about issues with the Linux APT repo, but 403 Forbidden specifically is a new symptom. Let me know the answers to the questions above.
Additional context - after executing apt update it points out that Cursor repo is no longer signed E: The repository ‘https://downloads.cursor.com/aptrepo stable InRelease’ is no longer signed.
