How to upgrade sed on RHEL 8?

Question

I'm on a RHEL 8 system and by default sed 4.5 was installed.

[root@192 ~]# rpm -qf `which sed`
sed-4.5-2.el8.x86_64
[root@192 ~]#

Since I want to use the --debug option to debug some sed commands, I have to upgrade sed. When I try to uninstall sed, I found a lot of other packages depend on it:

[root@192 ~]# rpm -e sed
error: Failed dependencies:
    /bin/sed is needed by (installed) os-prober-1.74-6.el8.x86_64

    /usr/bin/sed is needed by (installed) groff-base-1.22.3-18.el8.x86_64
[root@192 ~]#

In this case, what's the proper way to upgrade sed? I also tried to install a new version directly:

[root@192 ~]# rpm -ivh https://download-ib01.fedoraproject.org/pub/fedora/linux/releases/35/Everything/aarch64/os/Packages/s/sed-4.8-8.fc35.aarch64.rpm

    libselinux.so.1(LIBSELINUX_1.0)(64bit) is needed by sed-4.8-8.fc35.aarch64
[root@192 ~]#

But, as you can see, it also has some failed dependencies. Should I install these missing dependencies and try to install again?

Update

As jsbillings pointed out in the comment, I was using the wrong architecture of package. Below is the output of installing a x86_64 package.

You can’t install Fedora packages on RHEL.

Instead of trying to upgrade your sed, since you only want a newer version for its debugging capabilities, I recommend running a container:

sudo yum install podman
podman run -it --rm fedora:35

This will give you a Fedora container with a recent version of sed.
