I tried to install VMware Tools on my Fedora but after I copied the tarball into Desktop directory, I cannot use sudo any more. I tried chown to fix it but it didn't work either. I am new to Fedora and I found a similar problem in this link Changing ownership of ‘/usr/bin/’: Operation not permitted, however the answer only works for Ubuntu. I wonder how I can fix my problem.
[bunny@fedora gawk-5.1.1]$ su

su: cannot set groups: Operation not permitted
[bunny@fedora /]$ $sudo chown root /usr/bin
chown: changing ownership of '/usr/bin': Operation not permitted
