Regarding Changed repo URL and GPG key:

Please update APT sources list or YUM repos according to instructions in https://repo.avcdn.net/linux-av/doc/avast-techdoc.pdf:

For example:


DEB: deb http://deb.avast.com/lin/repo debian-buster release
  => deb https://repo.avcdn.net/linux-av/deb debian-buster release

RPM: baseurl=http://rpm.avast.com/lin/repo/dists/rhel/release
  => baseurl=https://repo.avcdn.net/linux-av/rpm/el$releasever/release

New GPG key can be downloaded from here: https://repo.avcdn.net/linux-av/doc/avast-gpg-key.asc

The old repositories are staying as they are, but new releases will be available only from the new repository.
