== Exclude Updates

== Excluding Packages From Transactions
=== WHY??
Sometimes it is useful to ignore specific packages from transactions, such as updates.
One such case, for example, could be when an update includes a regression or a bug.
DNF allows you to exclude a package from the transaction:
Sometimes we need block specific package because some people want to keep old and outdate software because it works fine compare to newer version in their case.
* With the Command Line
Until a fix is available you can block the offending package from updating by adding an option to the command.
* using the command line
----
sudo dnf upgrade --exclude=packagename
----
* In Configuration Files
* using its configuration files
It is also possible to add the exclude option to the configuration file. If you use a gui update application this is the best option. You will need root permission to edit this file so use su - or prefix the command with sudo. Add it to `/etc/dnf/dnf.conf` and Exclude packages of this repository.
You can add a line to `/etc/dnf/dnf.conf` to exclude packages:
----
excludepkgs=packagename
----
CAUTION: use **packagename** with glob https://en.wikipedia.org/wiki/Glob_(programming)[GLOBE] and separated by a comma, from all operations. Can be disabled using `--disableexcludes` command line switch.
This can also be added to the specific repository configuration files in `/etc/yum.repos.d/`.
https://en.wikipedia.org/wiki/Glob_(programming)[Globs] may be used here to list multiple packages, and each specification must be separated by a comma.
If you have used this configuration, you can disable it in individual DNF commands using using the `--disableexcludes` command line switch.
* **Locking the package version**
If you use a GUI update application which does not allow you to specify packages to exclude when they run, this method can be used.
You can use the `versionlock` plugin for DNF to keep it, is part of `dnf-plugins-core` or
=== Using the DNF Versionlock plugin
You can also use the DNF `versionlock` plugin to limit the packages that are included in a transaction.
It allows you to list what versions of particular packages should be considered in a transaction.
All other versions of the specified packages will be ignored.
The plugin is part of `dnf-plugins-core` package and can be installed using the command below:
----
sudo dnf install 'dnf-command(versionlock)'
----
Then add the version desired. For example:
To lock the currently installed version of a package, use:
----
sudo dnf versionlock add package
----
If you want to remove the locked version, use the delete option:
To remove the version lock, use:
----
sudo dnf versionlock delete package
----
The `list` command can be used to list all locked packages, while the `clear` command will delete all locked entries.
