I try changing the permissions of usr/lb with chown and don't work.

Changed the permissions to what? As you clearly saw, the /usr/lib has got to be non-writable by everyone. You do not mention your host (omission) but for a Ubuntu and a Fedora, the /usr and the /usr/lib permissions look like that (very close actually):

socratis@VB-Ubuntu:~$ ls -al /usr
total 124
drwxr-xr-x  11 root root  4096 Jul 19  2016 .
drwxr-xr-x  23 root root  4096 Jan 19 22:12 ..

socratis@VB-Ubuntu:~$ ls -al /usr/lib

The permissions are:

Code: Select all

ls -al /usr
drwxr-xr-x  12 root root   4096 sep  2 12:05 .
drwxrwxrwx  28 root root   4096 feb 21 11:12 ..

Any idea...??

Any idea...??

What do you mean any idea? It there! In plain sight!

ls -al /usr
drwxrwxrwx 202 root root  53248 feb 21 13:20 lib

Your /usr/lib directory is group/world writable. But besides that, you have a much, much bigger issue:

ls -al /usr
drwxr-xr-x  12 root root   4096 sep  2 12:05 .
drwxrwxrwx  28 root root   4096 feb 21 11:12 ..

Your root directory is group/everyone writable!

Really, that's the problem in the end!?
There isn't solution??
Can I fix the permissions or must re-install ubuntu?

[socratis]

Have you tried searching for "Ubuntu reset permissions to default"?

[cansinismo]

The solution was simple: sudo chmod 755 /usr/lib
