AdoptOpenJDK does not include a font configuration package, which Confluence relies on.
Atlassian installer has a script which will attempt to install the required font configuration package in the most common Linux distributions, however if your Linux distribution is not covered by our script, and does not include a suitable font configuration package, you will need to install one manually.
Solution
To tackle this problem, a fontconfig (or an equivalent library) should be installed prior Confluence installation. Refer to the documentation for your Linux distribution or preferred package manager for further information about how to do this.
Here are the commands to install font dependency in a number of common Linux distributions and package managers:
Installing the below packages may need a restart of your Confluence instance
Ubuntu
To install the fontconfig package on Ubuntu 18:
1
sudo apt install -y fontconfigCentOS
CentOS 7 does not work with fontconfig . You can install dejavu-sans-fonts as an alternative:
1
sudo yum install -y dejavu-sans-fontsRHEL
To install fontconfig on RedHat Enterprise Linux 7.5:
1
sudo yum install fontconfigLater versions, including RHEL8, should also work similarly.
On RHEL 6, it might be necessary to install both the dejavu-sans-fonts and the fontconfig packages:
1
sudo yum install -y dejavu-sans-fontsDebian
To install the fontconfig package on Debian 9.5:
1
apt-get update && apt-get install -y fontconfigFedora
To install the fontconfig package on Fedora 28:
1
dnf install -y fontconfigKnown issues
You can't use the Linux installer to install Confluence on OpenSUSE. You will need to install Confluence manually using the archive file. See CONFSERVER-57895 Installing Confluence in OpenSUSE Tumbleweed through the installer fails.
