I need to install Xvfb on Redhat 8, however the usual way doesn't work:
yum -y install xorg-x11-server-Xvfb
No match for argument: xorg-x11-server-Xvfb
Error: Unable to find a match: xorg-x11-server-Xvfb
From here How to install Xvfb (X virtual framebuffer) on Redhat 6.5? I tried the suggestion:
wget http://vault.centos.org/6.2/os/x86_64/Packages/xorg-x11-server-Xvfb-1.10.4-6.el6.x86_64.rpm
yum localinstall xorg-x11-server-Xvfb-1.10.4-6.el6.x86_64.rpm
But that gives:
Error:
Problem: conflicting requests
nothing provides libXdmcp.so.6()(64bit) needed by xorg-x11-server-Xvfb-1.10.4-6.el6.x86_64
nothing provides libXfont.so.1()(64bit) needed by xorg-x11-server-Xvfb-1.10.4-6.el6.x86_64
nothing provides libcrypto.so.10()(64bit) needed by xorg-x11-server-Xvfb-1.10.4-6.el6.x86_64
nothing provides xorg-x11-server-common >= 1.10.4-6.el6 needed by xorg-x11-server-Xvfb-1.10.4-6.el6.x86_64
Is there any way to install Xvfb on RH8?

Answer 1

Create the file /etc/yum.repos.d/centos8.repo
[CentOS-8]
name=CentOS-8
baseurl=http://mirror.centos.org/centos/8-stream/AppStream/x86_64/os/
enabled=1
gpgcheck=1
gpgkey=https://www.centos.org/keys/RPM-GPG-KEY-CentOS-Official
Then:
rpm --import https://www.centos.org/keys/RPM-GPG-KEY-CentOS-Official
dnf install -y xorg-x11-server-Xvfb
If you are trying to run something like cypress headless, you might also need some of these:
atk java-atk-wrapper at-spi2-atk gtk3 libXt mesa-libgbm libdrm

Answer 2

The only way to do this (without an RHEL subscription) is to do the following installs which work only when in this order:
yum install -y libXScrnSaver \
mesa-libgbm nss at-spi2-atk libX11-xcb \
ftp://ftp.redhat.com/pub/redhat/rhel/rhel-8-beta/appstream/x86_64/Packages/libxkbfile-1.0.9-9.el8.x86_64.rpm \
ftp://ftp.redhat.com/pub/redhat/rhel/rhel-8-beta/appstream/x86_64/Packages/xorg-x11-xkb-utils-7.7-26.el8.x86_64.rpm \
ftp://ftp.redhat.com/pub/redhat/rhel/rhel-8-beta/appstream/x86_64/Packages/xorg-x11-server-common-1.20.2-5.el8.x86_64.rpm \
ftp://ftp.redhat.com/pub/redhat/rhel/rhel-8-beta/appstream/x86_64/Packages/xorg-x11-xauth-1.0.9-12.el8.x86_64.rpm \
ftp://ftp.redhat.com/pub/redhat/rhel/rhel-8-beta/appstream/x86_64/Packages/libXdmcp-1.1.2-11.el8.x86_64.rpm \
ftp://ftp.redhat.com/pub/redhat/rhel/rhel-8-beta/appstream/x86_64/Packages/libXfont2-2.0.3-2.el8.x86_64.rpm \
ftp://ftp.redhat.com/pub/redhat/rhel/rhel-8-beta/appstream/x86_64/Packages/xorg-x11-server-Xvfb-1.20.2-5.el8.x86_64.rpm;
I don't know why it's so difficult.

The following docker file fixed it for us using UBI 8 openjdk.
We added the CentOS repository and enabled it.
