I have done all the steps required to run Katoolin, but I still get the message: sudo: unable to execute /usr/bin/katoolin: No such file or directory

Now I am able to do the chmod +x command w/o the system returning an error. However, when I go into /usr/bin and search for katoolin I find it, a 51.3kb file. Here's the issue under permissions it lists root(owner no read no write, group none), but I cannot click the drop down boxes, executable box is greyed out? Security context is unknown.

The chmod command is successful in terminal, but no change takes place when I view properties? I am at a complete loss. How can I get it to execute?

  • For the katoolin file in /usr/bin these are the current permissions with ls -l katoolin: root@Cyberdyne101:/usr/bin# ls -l katoolin ---x--xrwx 1 root root 51305 Nov 16 18:57 katoolin – Darkk Matter Nov 17 '17 at 00:39

    If /usr/bin/katoolin is a script, then it will need to be readable as well as executable – steeldriver Nov 17 '17 at 00:45
  • Well I'm still getting the same error, and I now have read and write. root@Cyberdyne101:/usr/bin# ls -l katoolin -rwxr-xrwx 1 root root 51305 Nov 16 20:00 katoolin root@Cyberdyne101:/usr/bin# sudo katoolin sudo: unable to execute /usr/bin/katoolin: No such file or directory I would also like to add I find it strange that is lists execute as a permission with ls -l, but when I right-click the file and go to Properties/Permissions all drop down boxes are greyed and executable box is greyed and no execute is listed under Owner or Group? – Darkk Matter Nov 17 '17 at 01:05
