How to install Xvfb on RH8?

Question

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?

No, epel doesn't have it either. I will add an answer with the unfortunate solution. — automaton, Dec 15 '20 at 18:51

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

it says This command has to be run with superuser privileges (under the root user on most systems). you have any other way around, thanks — Avinash jain, Sep 07 '22 at 10:44

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.

FROM registry.access.redhat.com/ubi8/openjdk-8

USER 0

RUN adduser --system non-root

ARG CERTIFICATES_DIR

# Copy root CA certs
COPY ${CERTIFICATES_DIR}/AAAAAAAAAAAA.crt /etc/pki/ca-trust/source/anchors/
COPY ${CERTIFICATES_DIR}/BBBBBBBBBBBB.crt /etc/pki/ca-trust/source/anchors/
COPY ${CERTIFICATES_DIR}/CCCCCCCCCCCCC.crt /etc/pki/ca-trust/source/anchors/

# Install CA certs
RUN update-ca-trust

RUN mkdir /app && chmod g+rwx /app

ARG APPLICATION_CLASS
ENV APPLICATION_CLASS=${APPLICATION_CLASS}

ARG DEPENDENCY_DIR

COPY ${DEPENDENCY_DIR}/BOOT-INF/lib /app/lib
COPY ${DEPENDENCY_DIR}/META-INF /app/META-INF
COPY ${DEPENDENCY_DIR}/BOOT-INF/classes /app


RUN chmod -R g+rwx /app/*

RUN printf '[CentOS-8]\nname=CentOS-8\nbaseurl=http://mirror.centos.org/centos/8-stream/AppStream/x86_64/os/\nenabled=1\ngpgcheck=1\ngpgkey=https://www.centos.org/keys/RPM-GPG-KEY-CentOS-Official' >> /etc/yum.repos.d/ubi.repo
