I keep getting error:plug in needed to view content when ever I want to watch certain videos on certain sites... this was just a matter of installing flash-plug in on my fedora 22 laptop. But when I try to install it on my Centos 6.6 laptop I'm getting this in the terminal :

[root@horriblehost /]# yum install flash plug-in
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
Loading mirror speeds from cached hostfile

 * updates: centos.mirror.constant.com
http://linux.dropbox.com/fedora/6/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: Dropbox. Please verify its path and try again
[root@horriblehost /]# 

I'm not sure why references to dropbox keep popping up. My dropbox is working... Any help? I would really like to get flash working. I'm new to this Linux thing ( but loving it).

Have you configured your CentOS 6.6 to use a repository that contains flash-plugin, RepoForge for example?

The dropbox error occurs because http://linux.dropbox.com/fedora/6/repodata/repomd.xml does not exist. CentOS is not listed at http://linux.dropbox.com. You can disable the repository temporarily with:

yum install flash-plugin --disablerepo=Dropbox

or make it persistent by setting:


in /etc/yum.repos.d/Dropbox.repo or whatever the dropbox repo file is named.


Please note that Flash is unsupported on Linux. This link provides more information.

As requested, here are some informational links about repositories and YUM:

Setup and Use repositories


  • This worked for installing flash-plugin! The --disablerepo=Dropbox worked like a charm. I will disable the repo for good next. Thank you. I'm still not sure how the repo thing works, suggestions for reading? I tried to up vote your answer but I guess I don't have much of a reputation around here, lol...

In the syntax of the command you have written, yum is attempting to install two packages: flash and plug-in.

You got the name wrong. Try yum install flash-plugin.

NOTE: Alternatively, you can install Adobe Flash player manually from their website, untar the file, copy libflashplayer.so to ~/.mozilla/plugins, and copy all of the files provided in usr (from the untar'd flash player file) to /usr using cp usr/* /usr.

  • when I try copying /usr* to /usr it says 'omitting' to every file it tries to copy ( there are three in there)
