EPEL Repo problem

newbie14 · 10-10-2012, 09:39 PM

Dear All,
I have tried to install the EPEL repo into my centos 6.3 via this method yum -y install /path/to/epel-release-6-7.noarch.rpm. There after now I have tried to yum install any thing else for e.g as below I get the error.

Code:

yum install logwatch
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

Here is some analysis results.

Code:

 a) rpm -q epel-release

How could I resolve this issue? Thank you.

"cat /etc/yum.repos.d/epel.repo" would be the most useful thing to show us really.

This often ends up being an inability to resolve the hostname being specified in the repo. A "yum clean all" can sometimes blow out some cobwebs too though if it's not something like that.

John VV · 10-11-2012, 04:46 AM

please add the output of

Code:

su -
yum repolist all

and also install the REQUIRED yum plugin "yum-priorities"
and CONFIGURE IT!!!!

see the install instructions on the wiki
http://wiki.centos.org/AdditionalResources/Repositories
and pay attention to ALL the warnings in the section
"Third Party Repositories"
and
"Extra Packages for Enterprise Linux (EPEL)"
- the plugin -
http://wiki.centos.org/PackageManagement/Yum/Priorities

just because it is in the folder"/etc/yum.repos.d"
dose not mean that it is turned on

Also try uninstalling "fastestmirror"
it is known to cause more problems that it tries to solve
and mostly is a royal pain in the "bleep"

Dear Kewpie,
I have done the yum clean all and below is the results you required.

yum -y install /path/to/epel-release-6-7.noarch.rpm

you might want to get out of the habit of using the VERY dangerous "-y" ( yes to ALL ) option
look in the yum log to see what else that command installed
/var/log/yum.log
if you are lucky then ONLY that repo will have been installed
if you are unlucky then it grabbed other programs also

and the rebuild of the rpm database DID NOT work ?? right
this command

Code:

su -
----- your root password when asked for-----
rpm --rebuilddb
yum clean all
yum update

that did NOT fix it ????

try this command to add a repo list of epel-release

Code:

# rpm -Uvh http://bit.ly/KANG3P

once done

Code:

# yum repolist

newbie14 · 10-13-2012, 12:25 PM

Dear John,
The yum.log seem to be empty. Below are the commands you suggested and still the same problem.

John VV · 10-13-2012, 07:49 PM

have you uninstalled fastmirror?
is is known to CAUSE many many problems
while only sort of maybe works for solving a slow update form a over taxed mirror.
( i have never had it work well)

Quote:

THAT is imposable !!!!
you did get updates
they WILL be listed
YOU also INSTALLED the "epel-release"
yum WILL HAVE LOGGED THAT

and

Are you behind a router ?

not very wise installing random rpms from random strangers from UNSIGNED sources
that is a VERY fast way to get your computer turned into a zombie

NOW while i am mostly sure that that rpm is ?? mostly?? safe ???
there is NO WAY of knowing IF it might have been tampered with( other than actually running "diff" on it to compare it to the rpm in the repo )

that is why yum checks the encryption signature to the OFFICIAL signature from the OFFICIAL repo.

newbie14 · 10-14-2012, 12:44 PM

Dear John,
What is the right command to uninstall fastmirror? Beside this yum.log file there is another one withsome dates as the name in that I can see a number of entry regarding the yum updates. So what should be my next step? Thank you.

John VV · 10-14-2012, 09:17 PM

you might want to look on the wiki
http://wiki.centos.org/PackageManagement/Yum
from the install instructions for the plugin
http://wiki.centos.org/PackageManage.../FastestMirror
edit
"/etc/yum/pluginconf.d/fastestmirror.conf"
and change the "enabled=1" to "enabled=0"

newbie14 · 10-19-2012, 10:58 AM

Dear John,
I have disabled it accordingly and run the yum update command and below is the results. I guess is still got a problem here right?

John VV · 10-19-2012, 04:44 PM

i just downloaded THE CORRECT
( and in comparing it to what YOU posted above)
you installed a messed up rpm - one that is pointing to THE WRONG location
epel-release-6-7.noarch.rpm
that is using the CORRECT web address

by installing a random rpm from some random source you installed the WRONG files

uninstall that mangled and incorrect BAD repo you installed from some random source -- it is BAD.

Code:

su -
yum remove epel-release
rpm --rebuilddb
yum update

THEN INSTALL the CORRECT ONE !!!
From the EPEL web site!!!
see the CentOS wiki
on installing third party repos
http://wiki.centos.org/AdditionalResources/Repositories
the correct rpm IS listed-- and is THIS ONE

http://dl.fedoraproject.org/pub/epel...6-7.noarch.rpm
and is listed on the epel web site
http://fedoraproject.org/wiki/EPEL

Ahhh but generally speaking $basearch matters, doesn't it?

[EDIT]No, it doesn't matter as both i386 and x86_64 packages share the same SHA1 hash (96C6A8F666C4656037F06CEB769E625B062F567D) and contain the same files.[/EDIT]

I have tried your steps and still failed as below. I am sorry with my bad problem here. Thank you.
