My ubuntu is 12.04LTS
I was used apt-get to install opera
and cowsay
. I've tried to execute them, but they all said
ubuntu@ubuntu:~$ cowsay
bash: /usr/games/cowsay: Permission denied
ubuntu@ubuntu:~$ opera-next
bash: /usr/bin/opera-next: Permission denied
I've already tried chmod a+x
them but they won't work
Here is mount output
