First of all, I installed Elastic Agent by DEB successfully, but I realize that cannot upgrade, so I uninstall Elastic Agent and remove installation layout of Elastic Agent. ![image](https://us1.discourse-cdn.com/elastic/original/3X/1/4/1424a01b7b1da399686369ffe54a189ff3df5081.png) And now when I install by Linux Tar, it fails and shows this error. ![image](https://us1.discourse-cdn.com/elastic/original/3X/3/f/3f93040ca25bdf57706b4e1ce21db99718f92357.png) ---

Hi @pntmky Welcome to the community! First please do not post images of text, they are hard to read, (some people can not read them at all) the can not be searched or debugged please post the text and format it. > [@pntmky](#): > > so I uninstall Elastic Agent and remove installation layout of Elastic Agent. Exactly How did you remove the elastic agent? And did you stop it before ... perhaps it is still running... did you check? Is there still an old `/usr/bin/elastic-agent` ? ---

I removed elastic agent by command "rm -r" and folder /usr/bin/elastic-agent has been removed ---

I think you should have used the package remove... Perhaps you should refer to the documention > **[Uninstall Elastic Agents from edge hosts | Fleet and Elastic Agent Guide \[8.5\]...](https://www.elastic.co/guide/en/fleet/current/uninstall-elastic-agent.html)** Perhaps run the uninstall manually `sudo /opt/Elastic/Agent/elastic-agent uninstall` ---

I follow this guide to uninstall Elastic Agent. In step 4, I manually remove Elastic Agent files from my system, because I'm not sure where the files are installed, so I remove all files in installation layout locations by `rm -r` command. And now I cann't install Elastic Agent by Linux Tar since installation layout locations have been removed. ---

I suspect perhaps you removed more than you should have... > [@pntmky](#): > > and folder /usr/bin/elastic-agent has been removed That is not a folder... It's not clear what actually you have removed... Are you still getting the same error? Check the permissions on `/usr/bin/elastic-agent` ---

`/usr/bin/elastic-agent` does not exist any more after I removed, I try to recreate it and copy content from other machine installed Elastic Agent successfully " **#!/bin/sh** **exec /opt/Elastic/Agent/elastic-agent $@**", but after that, it appears a new error that is " **/usr/bin/elastic-agent: 2: exec: /opt/Elastic/Agent/elastic-agent: not found** **Error: enroll command failed for unknown reason: exit status 127**". I continuously copy `/opt/Elastic/Agent` to create a new file but it fails, because it allows copy only `data` folder, vault folder and other files include `elastic-agent` cannot be copied, and I think each machine has a unique file elastic-agent. How do you know to create it again? ---

I do not believe You can create it copy it by hand... I am not what you did when you cleaned up... Perhaps reinstall via the deb package and then try to in remove using the deb package. Then try again ---

Thanks for your supporting, I uninstall by command `apt-get --purge` and check status to check for certain it stops and reinstall by Linux tar ---
