I’m coming across this error below when I run: sudo yum update

I see that the update is expecting a file to be removed. My plan was to find it and remove and then try the update again. However, find -iname "python-augeas-0.4.1-5.el7.noarch" doesn’t return anything for me, so I have my doubts that removing that file is the way to go.

Admittedly I’m not a sys admin or even very competent when it comes to stuff like this. Any help is appreciated. Thanks.


EDIT 1:

As suggested by Michael Hampton, here are the permissions and attributes:

$ ls -ld /usr/lib/python2.7/site-packages/python_augeas-0.5.0-py2.7.egg-info
drwxr-xr-x. 2 root root 4096 Jun 29  2015 /usr/lib/python2.7/site-packages/python_augeas-0.5.0-py2.7.egg-info


$ lsattr -d /usr/lib/python2.7/site-packages/python_augeas-0.5.0-py2.7.egg-info
---------------- /usr/lib/python2.7/site-packages/python_augeas-0.5.0-py2.7.egg-info

EDIT 2:

I uninstalled the package with sudo yum remove python-augeas. I then reinstalled with the following error:

$ sudo yum install python-augeas

My answer:


This happens because yum could not remove the old copy of the named file, /usr/lib/python2.7/site-packages/python_augeas-0.5.0-py2.7.egg-info.

This may be because the permissions are set incorrectly, or an immutable attribute is set.

Check the permissions and attributes for the file, and fix any problems. Then try the update again.

ls -ld /usr/lib/python2.7/site-packages/python_augeas-0.5.0-py2.7.egg-info
lsattr -d /usr/lib/python2.7/site-packages/python_augeas-0.5.0-py2.7.egg-info
