![]() ![]() RedHat Bugzilla does contain bug reports from users of dnf on Centos 7 and RedHat employees did work on them.on the other hand, there are also arguments for the thesis that it is supported and maybe that support is just well not documented and updated (in a typical open source project way □)? On the Centos blog the latest info about this is an article from 2018 - and the last question there - "Is it safe to use yum4/dnf on CentOS 7?" - has been unanswered for more than 1 year (since Dec 2019). Change the Hostname Method 1: Using the hostnamectl command. For releases before CentOS 7 - minor versions are incremental (6.0, 6.1, 6.2, etc.). As you can see from the image above, the current hostname is set to localhost.localdomain. As an example, CentOS Linux 7 (1406) means June 2014 and CentOS Linux 7 (1503) means March 2015. The Centos wiki page about using dnf on Centos 7 as yum4 - is not up to date as it is referring to Centos 7.5, released in 2018. Since minor versions of CentOS are point in time releases of a major branch, starting with CentOS Linux 7, CentOS Linux uses a date code as the minor version. But after running it with dnf migrate it errored with RuntimeError: Exec failed: no such table: ans_cmdline. ![]() ![]() but the command provided did not work for me as there is no such package as python-dnf-plugins-extras-migrate - this plugin is in the dnf-plugins-core package instead. This dnf FAQ entry says that it is safe to install dnf next to yum and provides a tool for migrating the history from yum to dnf. 4.0.9, from Nov 2018 ( appropriate dnf changelog entry), while the current latest version is 4.5.2 (from Dec 2020). but it in fact the dnf RPM package for Centos 7 is available in the Centos extras repo, but it is v. The dnf GitHub project's README provides info how to install it only for Fedora and states "In other RPM-based distributions you need to build all the components from their sources.". There are multiple arguments for the thesis that it is not supported: ![]()
