yum unable to locate package

[grittt]

I want to install VLC, but yum is unable to locate the package - see the Terminal output below.

How can i find out which repository contains the VLC package?

$ yum info vlc
\Loaded plugins: fastestmirror, langpacks
https://copr.fedorainfracloud.org/coprs ... repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
Trying other mirror.

You'll need to add a repo that supplies vlc if you want to install it. I know of 2: nux-dextop and possibly rpmfusion. I use the first. You can find more info in the wiki. Additional packages are often in 3rd party repos. Information on additional CentOS repos is available at http://wiki.centos.org/AdditionalResources/Repositories Pay attention to the reference on yum-priorities.

Thanks for the info. However, I'm getting a transaction lock error when trying to add the nux-dextop repo (copied and pasted the command for EL7 from http://li.nux.ro/repos.html).

$ sudo yum -y install epel-release && rpm -Uvh http://li.nux.ro/download/nux/dextop/el ... noarch.rpm

What is the -Uvh for?
Also, what is the correct URL - to replace https://copr.fedorainfracloud.org/coprs ... repomd.xml: ?

Code: Select all

man rpm

Searching can be done via '/' and '?'.

$ sudo yum -y install epel-release && rpm -Uvh http://li.nux.ro/download/nux/dextop/el ... noarch.rpm

You ran sudo yum which makes yum run as root but your && rpm is not sudo'ed so runs as you and has no permission...

Thanks, that helps.

$ sudo yum -y install epel-release && rpm -Uvh http://li.nux.ro/download/nux/dextop/el ... noarch.rpm

You ran sudo yum which makes yuum run as root but your && rpm is not sudo'ed so runs as you and has no permission...

But if I don't run it as sudo, this happens:

$ yum -y install epel-release && rpm -Uvh http://li.nux.ro/download/nux/dextop/el ... noarch.rpm
Loaded plugins: fastestmirror, langpacks
You need to be root to perform this command.

I'm not sure what this means: "your && rpm is not sudo'ed". Sorry, I'm still new to CentOS.

You ran two commands like

sudo yum .... && rpm ...

and what you should have run was

sudo yum ... && sudo rpm ...

The && is a command separator and thus sudo applies to the first command (yum) but not to the 2nd (rpm).

I didn't understand the &&. Now I see that the epel-release is already installed on my system, so I've run the second command by itself, sudo rpm....... and the repo has installed ok. Cheers.

They're two separate commands separated by && which is a bash command shell thing which says run this if the return code from the 1st says it worked. However, sudo ran the first one and the second one was run without sudo so didn't work.

Try the following :

Code: Select all

sudo yum -y install epel-release && sudo yum install http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
