Have you done that? If it was me, I'd just comment out the line in whatever sources.d file(s) it is. The output says you should look at the apt-secure manpage, section 8. Remove that from your repo list however you added it. If anyone can help that would be awesome. W: Skipping acquire of configured file 'main/source/Sources' as repository ' unstable InRelease' does not seem to provide it (sources.list entry misspelt?) N: See apt-secure(8) manpage for repository creation and user configuration details. N: Updating from such a repository can't be done securely, and is therefore disabled by default. W: GPG error: stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D1742AD60D811D58Į: The repository ' stable InRelease' is not signed.
