How To Install repo on Ubuntu 22.04

In this tutorial we learn how to install repo on Ubuntu 22.04.

What is repo

Repo is a repository management tool that the Android developers built on top of Git. Repo unifies the many Git repositories when necessary, does the uploads to the Android revision control system, and automates parts of the Android development workflow. Repo is not meant to replace Git, only to make it easier to work with Git in the context of Android. The repo command is an executable Python script that you can put anywhere in your path. In working with the Android source files, you will use Repo for across-network operations. For example, with a single Repo command you can download files from multiple repositories into your local working directory.

repo is an unusual tool because it downloads all of its own Python modules using GPG-signed git tags, and stores those files as part of the project that it is working with. So this package just provides the wrapper script, which provides the GPG signing keys for verifying that the correct Python code was downloaded.

There are three ways to install repo on Ubuntu 22.04. We can use apt-get , apt and aptitude . In the following sections we will describe each method. You can choose one of them.

Install repo Using apt-get

Update apt database with apt-get using the following command.

After updating apt database, We can install repo using apt-get by running the following command:

How to add a Yum repository

There are a few different ways to add a Yum repository to your system, depending on what you need from the repository. Let’s look at three different options.

In most scenarios, when you build out a new system, you want to keep the installation footprint as small as possible. As a result, not all repositories and packages are typically installed at that time. Fortunately, repositories can be enabled and disabled through yum at any time, and there are many different sources you can choose from.

In this example, we’ll look specifically at Fedora, but the process is similar across other distributions utilizing yum .

Great Linux resources

It is always recommended you use a known repository, such as Extra Packages for Enterprise Linux (EPEL), which is hosted at fedoraproject.org. Or, you might need a specific version of MySQL, which is hosted at mysql.com. There are also circumstances where you might need to add a lesser-known repository, such as remirepo.net for versions of PHP, or even host your own repository.

Once you determine which repository you need, there are several different ways to install and enable it.

Install a repository .rpm

The first is to install an .rpm with the repository information. The following command installs the EPEL repository for CentOS 8:

# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm 

Set up only a section of a repository

In the case of needing a specific repository, as in the case of PHP 7.2, you first need to install the repo and then disable and enable repositories using yum-config-manager as follows:

$ sudo yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm $ sudo yum-config-manager --disable remi-php54 $ sudo yum-config-manager --enable remi-php72 

Manually set up a repository

The last method of configuring a yum repository manually, where we create a .repo file within /etc/yum.repo.d using a text editor. In this example, we will create the repository file for MySQL 5.7:

$ nano /etc/yum.repo.d/mysql57-community.repo [mysql57-community] name=MySQL 5.7 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql 

Now, let’s discuss the lines we configured. The first three lines contain the minimum information you need when creating a .repo file. The first line is the unique identifier for the section and is enclosed in [] :

Note: You can have more than section (repository) in a .repo file.

The second line in our file is the name we choose to describe the repository:

name=MySQL 5.7 Community Server 

The third line is the location ( baseurl ) of the repository. In this case, we are using HTTP to access it:

baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/ 

As we mentioned, the first three lines are mandatory to configure a repository. We have also configured three more options. In the first additional option, we configured the toggle enabled , where 0 is disabled and 1 is enabled:

In the last two lines, we configured our information related to GPG. The first of these lines is the toggle to check for GPG and the second is the location of the key you are checking against:

gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql 

To see a complete list of repository options, see the man page as follows:

Now that you have your new repository configured using one of these methods, you should verify that it is configured properly using the yum-config-manager command from earlier to enable and disable PHP sections:

# yum-config-manager mysql57-community 

This command returns the complete information for the repository:

[root@centos3 yum.repos.d]# yum-config-manager mysql57-community Loaded plugins: fastestmirror ================================================================================================= repo: mysql57-community ================================================================================================== [mysql57-community] async = True bandwidth = 0 base_persistdir = /var/lib/yum/repos/x86_64/7 baseurl = http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/ cache = 0 cachedir = /var/cache/yum/x86_64/7/mysql57-community check_config_file_age = True compare_providers_priority = 80 cost = 1000 deltarpm_metadata_percentage = 100 deltarpm_percentage = enabled = True enablegroups = True exclude = failovermethod = priority ftp_disable_epsv = False gpgcadir = /var/lib/yum/repos/x86_64/7/mysql57-community/gpgcadir gpgcakey = gpgcheck = True gpgdir = /var/lib/yum/repos/x86_64/7/mysql57-community/gpgdir gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql hdrdir = /var/cache/yum/x86_64/7/mysql57-community/headers http_caching = all includepkgs = ip_resolve = keepalive = True keepcache = False mddownloadpolicy = sqlite mdpolicy = group:small mediaid = metadata_expire = 21600 metadata_expire_filter = read-only:present metalink = minrate = 0 mirrorlist = mirrorlist_expire = 86400 name = MySQL 5.7 Community Server old_base_cache_dir = password = persistdir = /var/lib/yum/repos/x86_64/7/mysql57-community pkgdir = /var/cache/yum/x86_64/7/mysql57-community/packages proxy = False proxy_dict = proxy_password = proxy_username = repo_gpgcheck = False retries = 10 skip_if_unavailable = False ssl_check_cert_permissions = True sslcacert = sslclientcert = sslclientkey = sslverify = True throttle = 0 timeout = 30.0 ui_id = mysql57-community/x86_64 ui_repoid_vars = releasever, basearch username = 

With your repository installed, you are ready to use yum to install the packages located there!
