I am at a loss.
All that I get are error messages. And it is not random.
All Terminal commands are reporting errors.

I was advised to re-download Lubuntu and to be sure that the MD5Sum was correct.
I did and it is correct. Then I ran a check for errors on the CD, no errors found.
Then I booted to Try Lubuntu Without Installing. It went to Desktop very fast.

I started to write some terminal commands: sudo, apt-get,mkdir, wget,sh all give error like this one

sudo: command not found

It doesn't matter if you combine these with other commands you will always get error messages.
For example when I try to install something:

sudo apt-get install (any Program):

This will yield nothing but error messsages:

"No command sudo found, did you mean:

Command 'sudo' from package 'sudo-ldap' (universe)
Command 'sudo' from package 'sudo' (main)"

And so on...
I didn't write down the other error messages for apt-get...
the error list sometimes fills up half the Terminal screen. So I tried the CD on another completely different computer.
Once again booted to the Desktop very fast. When I started to input Terminal Commands, I see the same exact error messages. No changes.

I am at a loss. I cannot do anything.

Is the Download itself corrupt even though the MD5 is verified correct? I downloaded directly from the Lubuntu Home Page.


Is there any way to fix this issue?
Any help would be greatly appreciated. Thank you.

  • Please post a command and the error messages that it generates. – StallionSA Jun 17 '14 at 6:54
  • Write from prompt echo $PATH and verify if you have /bin, /sbin and` /usr/bin in it. After try to execute /bin/mount to see what is mounted on your system... – Hastur Jun 17 '14 at 6:54
  • If you do not have /bin and /usr/bin in your PATH variable you can add with PATH="/usr/bin:/sbin:/bin:/usr/local/bin:"${PATH}. Try to see if the directories exist e.g. ls /bin. Include information as name of the iso image you download , link, MD5 checksum, output of mount and echo $PATH in your question editing with this link. – Hastur Jun 17 '14 at 7:21

Usually, all user commands are in /bin and /usr/bin or /usr/local/bin directories. So if it is not in your path try to add directories to your search path as follows:

export PATH=$PATH:/bin:/usr/local/bin
  • I am once again re-downloading and re-burning to disc. Then I will reinstall instead of utilizing Try Lubuntu Without Installing. It will be alot easier to post commands and error messages while Lubuntu is installed. That way I can work within Lubuntu without having to switch Computers.Please give me until the weekend. Thank you for all your help and patience. I really very much appreciate all the advice and guidance. – user236378 Jun 18 '14 at 3:08
  • seems to be working better now. . .not as many error messages. . .however the "lock" screen keeps appearing after the screensaver initializes. . .is there a way to eliminate the lock screen? Is there a configuration file? The "Lock Screen when going for suspend/hibernate" is unchecked in the Power Manager section. – user236378 Jun 19 '14 at 21:16
  • I removed light-locker but the lock screen still appears after the screensaver initializes. If there is a fix please advise. Lubuntu is working well at the moment except for the lock screen. No more errors. Thank you for the assistance. – user236378 Jun 20 '14 at 23:12
  • Is this what you mean? link – Babbzzz Jun 22 '14 at 2:41
  • I was able to fix the lock screen issue by deleting ALL light locker configuration files after deletion of light locker. Thank you for all of the assistance. – user236378 Jun 24 '14 at 3:23
