but I got the following error:

2020-06-25 15:17:46 [INFO ] Removing previous docker-compose image.

Error: No such image: linuxserver/docker-compose:latest

2020-06-25 15:17:46 [INFO ] Installing latest docker-compose.

ln: failed to create symbolic link '/usr/bin/docker-compose': File exists

2020-06-25 15:17:46 [FATAL ] Failed to create /usr/bin/docker-compose symlink.

2020-06-25 15:17:46 [ERROR ] DockSTARTer did not finish running successfully.

I do not know how to correct this error. I searched google, reddit, the forum and discord, but have not found a solution.

Can someone provide more information for how to fix this error?

Thank you in advance.

Why are you installing the docker-compose docker when docker-compose is already installed on the system?

sj136 · 26. Juni 2020

I was following the video and they referred to

https://dockstarter.com/

Which gives the following install commands as a user in sudo group:

sudo apt-get install curl git

bash -c "$(curl -fsSL https://get.dockstarter.com)"

and then I got the error.

I guess you will have to remove docker-compose that omv-extras installs. You probably should remove docker with the button in omv-extras since the script you are running installs docker too.

I would start over and not install docker compose. You don't have to if you follow the video. I do not.

Glad it's not just me - I followed the same videos and have ran into the same error!

I also have had the same error today, but already had DockStarter successfully installed. This error came up when I selected the upgrade option in the GUI and then selected yes to run docker-compose.

I've managed to solve it by running

Code

sudo unlink /usr/bin/docker-compose

to remove the old symlink. Then running dockStarter again, in my case

Code

ds -c

But note according to the docs, the `ds` shortcut is only available when:

Code

NOTE: ds shortcut is only available after the first run of
       sudo bash main.sh

So you may have to go back to the original tutorial again to pick up from where you left off.

Hope that helps
