Sometimes when installing a package on Linux you will come across the following error:
The error reads the following:
Error: Problem: cannot install the best candidate for the job - nothing provides daemonize needed by jenkins-2.303.3-1.1.noarch (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
1. Cause
The cause of this error is that the daemonize package is required, but it cannot be found in the repositories available on the system. Thus it throws the error that you see above.
Daemonize is a helper tool which runs a command as a Unix daemon, and is required by many packages, such as Jenkins.
2. Solution
In order to fix this error we need to install a repository with contains this package. For most RHEL based distributions the EPEL repository, (which stands for Extra Packages for Enterprise Linux) can be used. In order to install the EPEL repository on CentOS 8 / RHEL 8 / AlmaLinux 8, run the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
When the prompt asks you for a confirmation, type “Y” or “yes”.
After the epel-release repository is installed, refresh the internal repository list:
sudo dnf repolist
The command above will print a few lines, one of the lines should contain the entry Extra Packages for Enterprise Linux 8 – x86_64. If you see this message the EPEL repository is installed correctly.
Now try and install the daemonize package again. This time it should work:
sudo dnf install daemonize
If you did everything correctly, the output should be the following:
