I am having a trouble whenever I want to install a new package or run
sudo apt-get update with the following message:
W: The repository 'http://packages.elementary.io/appcenter xenial Release' does not have a Release file. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details. E: Failed to fetch http://packages.elementary.io/appcenter/dists/xenial/main/binary-i386/Packages 403 Forbidden [IP: 188.8.131.52 80] E: Some index files failed to download. They have been ignored, or old ones used instead.
