Now, let’s see the fixes for this error.

How we fix the yum PycURL error 22?

Our Support Engineers with expertise in Server Administration fixes yum errors quite often. Let’s see how we fix this.

1. yum error 22 due to unsupported repository

Recently, our customer had PycURL error 22 while yum upgrade in the CentOS system. Our Support Engineers re-executed the command to troubleshoot the error. The upgrade terminated at one of the repositories with an error message.

[Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found." Trying other mirror.

Hence we checked the repo file. For this, we open the yum repo file. Editing these files need root access.

vi /etc/yum.repo.d

Further, we checked for the module which caused the error. And we disabled it.

But this didn’t fix the error.  So, we removed this manually.

Finally, we used the command to clean the yum.

yum clean all

And this fixed the error.

2. Correct the proxy setting

In some cases, the corrupted proxy configuration causes errors.

Today, proxy servers are important security measures. That is, proxy servers acts as a security layer between the server and the Internet.

So, our Support Engineers check the config file. We edit the config file as a root user.

vi /etc/yum.conf

Here we fill the proxy setting and save the file.

Some customers have subscription managers like RHSM. In such cases, we update the proxy setting in their config file. For instance, for RHSM we update the

/etc/rhsm/rhsm.conf

3. Clear yum cache to fix PycURL error 22

Similarly, a corrupted local machine cache can also cause PycURL error. To fix this, we clear the yum cache using the command,

yum clear all

If the error persists, then our Support Engineers clear the cache folder.

rm -rf /var/cache/yum/*

Last but not least, connection errors or outdated OS versions can end up in errors. So, we check the system status and upgrade it if needed.
