Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

After installing the cursor.deb package on Linux Mint, running sudo apt update fails to sync the Cursor repository due to a missing public GPG key. This prevents the system from verifying the package source and stops further updates.

Err: https://downloads.cursor.com/aptrepo stable InRelease
The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 42A1772E62E492D6

Steps to Reproduce

  1. Download cursor.deb from the official website.
  2. Install via dpkg or gdebi.
  3. Run sudo apt update in the terminal.

Expected Behavior

The installation of the .deb package should automatically import the GPG key to /etc/apt/trusted.gpg.d/ or provide a post-install script to handle the key registration.
