Error unable to find a match pygpgme

Erlang is a functional, general-purpose, concurrent programming language and garbage-collected runtime environment built for concurrency, fault tolerance, and distributed application architectures. It is supported and maintained by Ericsson OTP product unit.

In this guide, we will install Erlang/OTP in a Fedora 35 Server/Workstation.

1. Updating the system

Let us ensure that our server packages are up to date using this command:

sudo dnf -y update

Let us also install some common packages

sudo dnf install vim -y

2. Installing Erlang

The Erlang package is distributed via Yum repositories on PackageCloud. Install the PackageCloud Yum repository using this command:

curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh | sudo bash

This is the output on my server

$ curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh | sudo bash

Generating yum cache for rabbitmq_erlang-source...

The repository is setup! You can now install packages.

Now we can install erlang from the added repos:

sudo dnf install erlang

3. Creating Hello world program

Create hello.erl file

vim hello.erl

Add this to the file

% This is a test Hello World Erlang Code
-module(hello).
-import(io,[fwrite/1]).
-export([helloworld/0]).

helloworld() ->
   fwrite("Hello from Citizix, Erlang World!n").

Compile it from the Erlang shell. Don’t forget the full-stop (“period“) at the end of each command:

$ erl
Erlang/OTP 23 [erts-11.2.2.7] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:1] [hipe]

Eshell V11.2.2.7  (abort with ^G)
1> c(hello).
{ok,hello}
2> hello:helloworld().
Hello from Citizix, Erlang World!
ok
3>

You have successfully installed Erlang in your system.

Conclusion

Thanks for using this tutorial for installing the Erlang programming language on your Fedora 35 system. For additional help or useful information, we recommend you to check the official Erlang website.

Question: This is Yashikha again and thanks for helping me out with the previous issue. Now I am stuck with another error while trying to install python-pip via the yum command. Following is the complete error message.

# yum install python-pip
Extra Packages for Enterprise Linux 8 - Next - x86_64 106 kB/s | 206 kB 00:01
No match for argument: python-pip
Error: Unable to find a match: python-pip

I did configure the EPEL repo before installing python-pip.

# yum --enablerepo=extras install epel-release
:::::::::
Upgraded:
epel-release-8-15.el8.noarch
Installed:
epel-next-release-8-15.el8.noarch
Complete!

What could be the issue?

Solution: Fix Unable to find a match: python-pip

Yashikha, the reason why you couldn’t find python-pip in the EPEL repo might be because it may not be called python-pip anymore. To find the exact name of the package, run the below command.

# yum info python*-pip


Available Packages
Name : python3-pip
Arch : noarch
Version : 9.0.3
Release : 8.el7

: and (ASL 2.0 or BSD)
Description : pip is a package management system used to install and manage
: software packages written in Python. Many packages can be found in
: the Python Package Index (PyPI). pip is a recursive acronym that
: can stand for either "Pip Installs Packages" or "Pip Installs
: Python".

Name : python34-pip
Arch : noarch
Version : 8.1.2
Release : 14.el7
Size : 1.7 M
Repo : epel/x86_64
Summary : A tool for installing and managing Python3 packages
URL : http://www.pip-installer.org
License : MIT and BSD and ASL 2.0 and ISC and Python and (ASL 2.0 or BSD)
: and LGPLv2+
Description : Pip is a replacement for easy_install. It uses mostly the
: same techniques for finding packages, so packages that were made
: easy_installable should be pip-installable as well.

Now you get to know the exact package name. Install it as below:

# yum install python3-pip

packagecloud::repo { 'username/publicrepo':
  type => 'rpm',
}

packagecloud::repo { 'username/privaterepo':
  type => 'deb',
  master_token => 'eae123bca276162f376b9614ba134fa7993624a8de0bb3a2',
}

packagecloud::repo { 'username/privaterepo':
  type => 'deb',
  master_token => 'eae123bca276162f376b9614ba134fa7993624a8de0bb3a2',
  server_address => 'http://my.internal.server.domain:1234/',
}

packagecloud::repo { 'deb repository for blah':
  fq_name => "username/blah",
  type => 'rpm',
}

packagecloud::repo { 'gem repository for blah':
  fq_name => "username/blah",
  type => 'gem',
}

Exec {
  path => [ "/bin/", "/sbin/" , "/usr/bin/", "/usr/sbin/" ]
}
