In the future please fill out the issue template properly, as this is painful to read through.

You can obviously see that the file size for docker-compose is wrong here - there's no way an executable would be 9 bytes in length. This is probably due to the fact that you're on an unsupported OS or architecture, but since you neglected to provide that information, I can't say for sure.
          
If you open the '/usr/local/bin/docker-compose' file, it would be definitely 'Not Found'.(9 bytes)

Same issue on Rock64 ubuntu bionic....

The docker-compose file is located in /usr/local/bin but the file is empty.

Now what?
I also have the same problem with 1.24.1 on Raspian.
Isn't Raspbian a 32 bit OS? The official docs state you can only run compose on 64 bit Linux.
So when you try to curl with $(uname -m) in the url path it won't populate with x86_64, so you're probably trying to access a release that doesn't exist.
          
@Rampelflik are you sure you're trying to access a real release? Check the output of $(uname -s)and $(uname -m) to make sure curl is trying to access the Linux-x86_64 release.
(If $(uname -m) outputs something other than x86_64, your OS is probably unsupported).
If that's working, check that the release you're trying to access actually exists here.
As @raksshet stated above, your curl call should look like this (or similar):

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

I am facing the same error
Using

sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
Output of uname -s : Linux

Output of uname -m : i686
          
@ADI10HERO 32 bit architectures are not supported (you're using i686), you need to be running a 64 bit processor and OS (i.e. uname -m must return x86_64) to install docker-compose this way. You might want to try installing via pip as suggested above.
For those trying to install on Raspbian (ARM64) or another unsupported architecture, you can install docker-compose via pip.
See https://github.com/docker/compose/releases/1.26.2 for downloads available in the latest release (note there's no docker-compose-Linux-i686)
          
you all folks are downloading a "Not Found" string returned by a 404 http status code. Your target file for target architecture doesn't exist.
/usr/local/bin/docker-compose: line 1: Not: command not found
the Not above is realated to what I've explained.
did you guys tried to run nano /usr/local/bin/docker-compose ?

I got a similar problem. It was because the version I tried to install was not actually there. So before downloading the docker-compose, make sure the release version exists from the link below:

https://docs.docker.com/compose/release-notes/
$ sudo apt install docker-compose

$ docker-compose version

$ sudo wget –O /usr/local/bin/docker-compose https://github.com/docker/compose/releases/download/1.25.0/docker-compose-Linux-x86_64

$ sudo chmod +x /usr/local/bin/docker-compose

$ docker-compose --version

$ sudo rm /usr/local/bin/docker-compose

$ ./docker.sh install
          
I ve got this error when trying to run docker-compose in travis. I solved the issue using :
sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
@Rampelflik are you sure you're trying to access a real release? Check the output of $(uname -s)and $(uname -m) to make sure curl is trying to access the Linux-x86_64 release.
(If $(uname -m) outputs something other than x86_64, your OS is probably unsupported).

@ADI10HERO answer is correct,  but notice that there have been a change in the link on github, and now the version number should look like v2.1.1 (not 2.1.1, i.e. include the v in the link)

This is the link that worked for me:
sudo curl -L "https://github.com/docker/compose/releases/download/v2.1.1/docker-compose-linux-x86_64" -o /usr/local/bin/docker-compose

love you, this works
          
I found that uname -s returns Linux with upper-case L, but the release binary on Github contains lower-case l inside its name.
nikel@nikel-PC:~/odm-payless/backend$ echo https://github.com/docker/compose/releases/download/2.1.1/docker-compose-`uname -s`-`uname -m`
https://github.com/docker/compose/releases/download/2.1.1/docker-compose-Linux-x86_64
          
if you are using macOS than first enter this command

sudo rm /usr/local/bin/docker-compose

to remove docker-compose installed through curl

than install it using

brew install docker-compose
          
To install or upgrade to the latest version every time for MAC (and will likely work for linux as well).
sudo curl -L "https://github.com/docker/compose/releases/download/$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep '\"tag_name\":' | sed -E 's/.*\"([^\"]+)\".*/\1/')/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose




    

This will fetch the latest version number and use that to download the latest and install it.

use this should work.

Thank you so much! this worked for me <3
          
you should follow this link in order to solve your issue:
sudo curl -L "https://github.com/docker/compose/releases/download/v2.11.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
you forget the v before the version thank you @AndrewOdiit also and when you inquire on version you should write: docker-compose version
          
@Abdurahman-hassan
Its silly, but yeah... I also forgot the 'v' in front of the version number
Old tutorials (< v2) don't use the 'v' in the URL, so easy to overlook.
Thanks
sudo rm /usr/local/bin/docker-compose sudo pip uninstall docker-compose
then sudo pip install docker-compose
then docker-compose --version
This work for me
Hi, only for said that this task works...

emi@nbdebian11:/usr/local/bin$

emi@nbdebian11:/usr/local/bin$ sudo docker-compose --version

docker-compose version 1.29.2, build unknown
I don't know build unknown mean.

I had the same issue when I try to setup on the Oracle-Linux-8.6-aarch64-2022.12.15-0 image. You can get more information here https://github.com/linuxserver/docker-docker-compose

And here's what I did

sudo curl -L --fail https://raw.githubusercontent.com/linuxserver/docker-docker-compose/master/run.sh -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
          
sudo curl -L "https://github.com/docker/compose/releases/download/$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep '\"tag_name\":' | sed -E 's/.*\"([^\"]+)\".*/\1/')/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
DonRichard's solution as seen above here and further above on the page is the best solution here. Have only  added the line for docker-compose to be executable. You get an uptodate version of docker-compose, and it also solves the issue:

/usr/local/bin/docker-compose: line 1: Not: command not found
Using linux but like he said its most likely to work on a Mac.
