Although my ssh file was located at /usr/bin/ssh, my sshd file was nowhere to be found.
I ended up discovering that it was actually in the /sbin/ file.
If you run into a similar problem simply run the same commands except on the /sbin/ folder:
chattr -i /usr/sbin/sshd
chattr -a /usr/sbin/sshdHi!
Google brought me here. This post was very useful for me, in my case with the error: unable to make backup link of `./usr/lib/php5/sessionclean' before installing new version: Operation not permitted
I just had to:
chattr -i /usr/lib/php5/sessionclean
chattr -a /usr/lib/php5/sessionclean
chattr +s /usr/lib/php5/sessionclean
chattr +u /usr/lib/php5/sessionclean
And it fixed my problem! Thanks a lot
Thanks you.
Problem solved here.
Thank you Falko,
This worked for me. Why the attributes are changed. Is it a work of hackers?

worked for me - stuck in the middle of a dist-upgrade and had the 'i' (immutable) flag set on this file --> /usr/lib/gvfs/gvfsd-metadata
A real lifesaver. Would like to know how this sort of problem happens though.
