How to install Opera Browser on CentOS 8 ?

To begin, You must have a root account or you can have some administrative privileges.

Then, you can use the following two different methods, to install Opera browser on your CentOS 8 system:

1. Download Opera rpm package using wget command

2. By adding the Official Opera repository

1. Download Opera rpm package using the Wget command

Open the command-line window 'Terminal' and enter the 'su' command in order to login as a root user. 

Now, perform the below-mentioned steps to install the Opera browser using this method:

i. First, you need to verify that either wget command-line utility is installed on your system or not. You can check the installation of the wget utility by using the following command:

# rpm -qa wget

In CentOS 8, the wget command is already installed. But, If in any case, it is not available then by typing the following command you can easily install it on your CentOS 8 system:

# yum -y install wget

ii. Download the Opera binary rpm package from the official Opera page by using the wget command-line utility on your system. Use the following command in order to download the Opera rpm package:

# wget https://download3.operacdn.com/pub/opera/desktop/66.0.3515.72/linux/opera-stable_66.0.3515.72_amd64.rpm

The above package will download into your system’s home directory.

iii. Once the download is completed, now you will install this downloaded rpm Opera package on your CentOS 8 system by using the ‘Yum’ package manager. Type the following command to install the Opera browser:

# yum install opera-stable_66.0.3515.72_amd64.rpm

During the installation, you will confirm the installation of Opera by pressing ‘y’ and then hit 'Enter'.

In a while, a 'complete' status will display on your system that represents the Opera browser has been installed on your system.

iv. You can open the opera browser on your system by using the application search bar. Click on the 'Activities' and then type 'Opera' in the application search box. The Opera browser icon will show in the search result.

Click on the Opera browser icon and a welcome page will display on your desktop.

This installation method will complete in the following steps:

i. You need to add the GPG key. Run the below-mentioned command to import this GPG key:

# rpm --import https://rpm.opera.com/rpmrepo.key

ii. Execute the following command in order to add the Official Opera browser repository on your system:

# tee /etc/yum.repos.d/opera.repo <<REPO
[opera]
name=Opera packages
type=rpm-md
baseurl=https://rpm.opera.com/rpm
gpgcheck=1
gpgkey=https://rpm.opera.com/rpmrepo.key
enabled=1
REPO

iii. Once the repository added to your system, type the following command to install the Opera browser on your CentOS 8 system:

# yum -y install opera-stable
