I dont know exactly why but since some days runs following errors when I run apt update:
Err:17 https://repo.charm.sh/apt * InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 03BBF595D4DFD35C
Reading package lists... Done
W: GPG error: https://repo.charm.sh/apt * InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 03BBF595D4DFD35C
E: The repository 'https://repo.charm.sh/apt * InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details

Heya,
The error you’re encountering means that the public key for the repository https://repo.charm.sh/apt is missing, which prevents apt from verifying the authenticity of the repository. This is a common issue when a repository’s signing key is not imported to your system.
To fix this issue, follow these steps:
You can manually download and add the missing public key. The error message mentions the key ID 03BBF595D4DFD35C, which you can use to retrieve the public key.
Run the following commands:
This command retrieves the missing key from the Ubuntu keyserver. If this doesn’t work, try a different keyserver:
After adding the key, you can verify that the key was successfully added by running:
Look for the key 03BBF595D4DFD35C in the output.
Once the key is added, update the package list again to see if the error is resolved:
This should now successfully update the package lists without the GPG error.
Alternative: Re-add the Repository
If the problem persists, the repository configuration might have changed. You can remove and then re-add the repository as follows:
- First, remove the repository configuration file (if applicable) under
/etc/apt/sources.list.d/:
Then, re-add the repository with the updated signing key by following the instructions on the official website for https://repo.charm.sh.
