Updated OpenSSH Incorrectly

kenrbnsn
Some of my users were having problems using SFTP and research via Google suggested that removing & reinstalling the openssh server would fix these problems, so I did the following from an SSH terminal session:
yum erase openssh-server yum install openssh-server /usr/local/cpanel/scripts/restartsrv_sshd
This seemed to fix the SFTP problems that were being seen, but now when WHM tries to update my cPanel version, I get these errors and the update dies.

How do I fix this problem? Is the fix as simple as
yum erase openssh-server
And then let WHM reinstall the package? Thanks in advance.

    Hello, It's possible one of the files associated with that RPM is not writable. Could you run the below command and let us know the output?
    lsattr /usr/sbin/sshd /usr/bin/ssh /usr/bin/scp
    Thank you.

    Hello, Try removing the immutable bit from the /usr/bin/ssh binary to see if that helps. EX:
    chattr -i /usr/bin/ssh
    Thank you.

    I did that command:
    # chattr -i /usr/bin/ssh # lsattr /usr/sbin/sshd /usr/bin/ssh /usr/bin/scp su---a-------e- /usr/sbin/sshd su---a-------e- /usr/bin/ssh -------------e- /usr/bin/scp
    I then tried to install the openssh-server via WHM. This is the result:

    Still not working. :(

    Hello, Please also remove the "a" attribute:
    chattr -a /usr/sbin/sshd chattr -a /usr/bin/ssh
    Also, are you aware of how those attributes were applied to those files? If not, I recommend consulting with your provider or a system administrator as it's not standard for those attributes to be applied. It indicates a third-party application or a person with root access applied those attributes to prevent the system from changing those binaries. Thank you.

    Thanks, that worked. As I said before, I screwed up by trying to fix the problem I was having and updated openssh-server incorrectly. Thanks for your help.
