How to Fix: Yum [Errno 14] PYCURL ERROR 22 - 404 Not Found

Infopackets Reader Steve T. writes:

" Dear Dennis,

I am running Centos 6 32-bit (i386) on a virtual machine and recently I started having 'PYCURL ERROR 22' every time I use 'yum list updates' or 'yum -y update' to list and download updates. The error message says '[Errno 14] PYCURL ERROR 22 - The requested URL returned error: 404 Not Found'. I have gone to the wiki.centos.org/yum-errors as the error message suggests, but have not been able to find a solution to this problem. Can you help? "

My response:

I asked Steve if he would like me to connect to his virtual machine using my remote desktop support service in order to have a closer look at the problem, and he agreed. Below I will discuss my findings.

How to Fix: Yum [Errno 14] PYCURL ERROR 22 - 404 Not Found

As the centos.org wiki suggests, the first thing to do is to clear the yum cache as it may be corrupt, which will result in the PYCURL ERROR 22. To do so, open a terminal window / SSH and enter in the following:

yum clean all
rm -rf /var/cache/yum/*

If that does resolve your problem, please have a closer look at the error message. In Steve's case it was the repo.ius.io mirror which was failing, as noted in the sample output below. In order to fix it, I went to the /etc/yum.repos.d directory and modified the ius.repo file in order to disable it.

Here is the sample output:

yum list updates

Trying other mirror.

To address this issue please refer to the below wiki article

https://wiki.centos.org/yum-errors

Disable Repository to Fix 'PYCURL ERROR 22'

If you note the above output (red bold text), it lists the URL that is causing the error (repo.ius.io). To fix the error you need to disable the repository via its configuration file, but this is really only a temporary fix to the issue as it does not replace the broken repository.

For the record, I attempted to open https: //repo.ius.io/6/i386/repodata/repomd.xml via the browser and it results in a 404 (file not found). After a bit more research, it appears that repo.ius.io has removed all i386 (Centos 6 32 bit) data from their server and currently only supports x64. This may be because Centos 6 is reaching its end of life (as of November 30 2020).

I am not familiar enough on how to replace this repository as it seems they have switched from using mirrors to a content distribution network (CDN) as of April 30, 2019. I also tried 'yum update ius-release' as the page suggests, but it made no difference.

To disable the repo.ius.io repository, do the following:

cd /etc/yum.repos.d

####show all files with ius in it:
ls -al |grep ius

-rw-r -- r-- 1 root root 669 May 1 12:00 ius-archive.repo
-rw-r -- r-- 1 root root 591 May 1 12:00 ius.repo                    <=== this file
-rw-r -- r-- 1 root root 669 May 1 12:00 ius-testing.repo

####modify the repo file:
nano -w ius.repo

[ius]
name = IUS for Enterprise Linux 6 - $basearch
baseurl = https://repo.ius.io/6/$basearch/
####was enabled = 1, set to 0
enabled = 0
repo_gpgcheck = 0
gpgcheck = 1
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-IUS-6

That's it! I hope that helps.

If anyone has any suggestions on getting the ius.repo to work again, please leave a comment below. For now, it appears to be taken offline - perhaps permanently.
