I'm confused why is this not working? Admin group is having access on the /opt directory and I'm the member of that group and still I can not make a new directory there.
vita@eldamar:/opt$ ll / total 120K drwxrwxr-x 14 root admin 4.0K Aug 26 20:32 opt/ vita@eldamar:/opt$ id uid=1000(vita) gid=1000(vita) groups=120(admin),4(adm),20(dialout),24(cdrom),27(sudo),1000(vita) vita@eldamar:/opt$ mkdir /opt/x mkdir: cannot create directory `/opt/x': Permission denied
Does anyone has any idea how this can happen? It is really strange :)
