Ubuntu team has its own vision for the snap (https://snapcraft.io/) service and that’s why they have moved the really big and difficult to maintain Chromium browser package in the snap package. Unfortunately, the snap has many issues with docker containers and in short, it is way difficult to run snap in a docker container. The user may just want not to mess with snap packages (despite this is the future according to the Ubuntu team) or like most developers they all need a browser for their tests executed in a container.
Whether you are a developer or an ordinary user this article is for you, who wants Chromium browser installed not from the snap service under Ubuntu 20.04 LTS!
There are multiple options, which could end up with a Chromium browser installed on the system, not from the snap service:
- Using Debian package and Debian repository. The problem here is that using simultaneously Ubuntu and Debian repository on one machine is not a good idea! Despite the hack, Debian packages are with low priority – https://askubuntu.com/questions/1204571/chromium-without-snap/1206153#1206153
- Using Google Chrome – https://www.google.com/chrome/?platform=linux. It is just a single Debian package, which provides Chromium-like browser and all dependencies requesting the Chromium browser package are fulfilled.
- Using Chromium team dev or beta PPA (https://launchpad.net/~chromium-team) for the nearest version if still missing Ubuntu packages for Focal (Ubuntu 20.04 LTS).
- more options available?
This article will show how to use Ubuntu 18 (Bionic) Chromium browser package from Chromium team beta PPA under Ubuntu 20.04 LTS (Focal). Bionic package from the very same repository of Ubuntu Chromium team may be used, too.
All dependencies will be downloaded from the Ubuntu 20.04 and just several Chromium-* packages will be downloaded from the Chromium team PPA Ubuntu 19 repository. The chances to break something are really small compared to the options 1 above, which uses the Debian packages and repositories. Hope, soon we are going to have focal (Ubuntu 20.04 LTS) packages in the Ubuntu Chromium team PPA!
An example of a Dockerfile installing Chromium (and python3 selenium for automating web browser interactions)
RUN apt-key adv --fetch-keys "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0xea6e302dc78cc4b087cfc3570ebea9b02842f111" \ && echo 'deb http://ppa.launchpad.net/chromium-team/beta/ubuntu bionic main ' >> /etc/apt/sources.list.d/chromium-team-beta.list \ && apt update RUN export DEBIAN_FRONTEND=noninteractive \ && export DEBCONF_NONINTERACTIVE_SEEN=true \ && apt-get -y install chromium-browser RUN apt-get -y install python3-selenium
First command adds the repository key and the repository to the Ubuntu source lists. Note we are adding the “bionic main”, not “focal main”.
From the all dependencies of the Bionic chromium-browser only three packages are pulled from the Bionic repository and all other are from the Ubuntu 20 (Focal):
..... Get:1 http://ppa.launchpad.net/chromium-team/beta/ubuntu bionic/main amd64 chromium-codecs-ffmpeg-extra amd64 84.0.4147.38-0ubuntu0.18.04.1 [1174 kB] ..... Get:5 http://ppa.launchpad.net/chromium-team/beta/ubuntu bionic/main amd64 chromium-browser amd64 84.0.4147.38-0ubuntu0.18.04.1 [67.8 MB] .....

Here is the whole Dockerfile sample file:
# # Docker file for the image "chromium brower without snap" # FROM ubuntu:20.04 MAINTAINER email@example.com #chromium browser #original PPA repository, use if our local fails RUN echo "tzdata tzdata/Areas select Etc" | debconf-set-selections && echo "tzdata tzdata/Zones/Etc select UTC" | debconf-set-selections RUN export DEBIAN_FRONTEND=noninteractive && export DEBCONF_NONINTERACTIVE_SEEN=true RUN apt-get -y update && apt-get -y upgrade RUN apt-get -y install gnupg2 apt-utils wget #RUN wget -O /root/chromium-team-beta.pub "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0xea6e302dc78cc4b087cfc3570ebea9b02842f111" && apt-key add /root/chromium-team-beta.pub RUN apt-key adv --fetch-keys "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0xea6e302dc78cc4b087cfc3570ebea9b02842f111" && echo 'deb http://ppa.launchpad.net/chromium-team/beta/ubuntu bionic main ' >> /etc/apt/sources.list.d/chromium-team-beta.list && apt update RUN export DEBIAN_FRONTEND=noninteractive && export DEBCONF_NONINTERACTIVE_SEEN=true && apt-get -y install chromium-browser RUN apt-get -y install python3-selenium
The desktop installation is almost the same as the Dockerfile above. Just execute the following lines:
