- Plesk for Linux
Cannot install Docker extension in Plesk on Ubuntu 18:
CONFIG_TEXT: E: Failed to fetch https://apt.dockerproject.org/repo/dists/ubuntu-bionic/InRelease 403 Forbidden [IP: 220.127.116.11 443]
E: The repository 'https://apt.dockerproject.org/repo ubuntu-bionic InRelease' is not signed.
ERROR:root:Command '['apt-get', '-qq', 'update']' returned non-zero exit status 100
Docker images catalog is empty.
Docker extension installs old repositories. This is Docker extension bug with ID EXTDOCKER-52 which will be fixed in future updates.
As workaround use Plesk on latest Ubuntu version that supports Docker Extension: Plesk Onyx on Ubuntu 16.04.
