Debian Groups Install fails on CLEAN install of Ubuntu20.04

Hello Ivan,

Sorry for the delayed reply.

It seems the issue is caused by the version 8.0.29 of MySQL. With the version 8.0.28 installation goes correctly. Please try this to avoid the issue:

  1. Remove all installed ONLYOFFICE components and MySQL.
  2. Download the scripts
    wget https://download.onlyoffice.com/install/install-Debian.sh
    wget https://download.onlyoffice.com/install/install-Debian/install-preq.sh
  3. Open the install-preq.sh script => find this section
# install
apt-get install -o DPkg::options::="--force-confnew" -yq wget \
        cron \
        rsyslog \
        ruby-dev \
        ruby-god \
        mono-complete=$mono_complete_version \
        ca-certificates-mono \
        mono-webserver-hyperfastcgi=$hyperfastcgi_version \
        nodejs=$node_version \
        mysql-server \
        mysql-client \

and add the version number to mysql-server and mysql-client:

mysql-server=8.0.28 \
mysql-client=8.0.28 \
  1. Save the script.
  2. Run the installation script bash install-Debian.sh

Let me know the results.
