RMF can not be installed because of the resource server has no response

[qingtian1771]

It seems I can not install it bacause the install server is no response.

I want to install is according the link: https://osrf.github.io/ros2multirobotbook/ , it says:

Next you will need to setup the source of RMF packages similar to the previous two steps. First authorizing the key:
curl -s http://rmf.servehttp.com/repos.key | sudo apt-key add -

Secondly adding the repository to the apt sources:
sudo sh -c 'echo "deb http://rmf.servehttp.com/ubuntu/main/ `lsb_release -cs` main" > /etc/apt/sources.list.d/rmf.list'

And now we are ready to install. Let's update our packages:
sudo apt-get update

And the update has some problems, it cannot access the rmf resource server.

tq@tq-sy:~$ sudo apt-get update

So when I install, it can not get the resource.

It seems fine from here:

$ sudo apt-get update
Get:1 http://rmf.servehttp.com/ubuntu/main focal InRelease [2807 B]
Get:2 http://rmf.servehttp.com/ubuntu/main focal/main amd64 Packages [36.9 kB]
Get:3 http://packages.ros.org/ros2/ubuntu focal InRelease [4670 B]  
..

Could you try again?

are you able to ping rmf.servehttp.com or access it through the browser?

[qingtian1771]

Strange. I cannot ping rmf.servehttp.com, but I can access it through browser. I still cannot access it through "sudo apt-get update", the same error as before.

[marcoag]

Ok, my bad suggesting the ping command as the server has the ping response off. The file your apt is failing to get seems accessible here:

http://rmf.servehttp.com/ubuntu/main/dists/focal/InRelease

Both, InRelease and the Release + signature files, seem to be available and accessible:

http://rmf.servehttp.com/ubuntu/building/dists/focal/

can you check if you are able to access this file? I tested from different locations and I can't seem to reproduce your issue...

[marcoag]

Since I can't reproduce the issue and there's been a few days of inactivity I will close this issue.

Hi, opening this thread again because I got similar issue while following this tutorial to install RMF. Seems that it cannot access the rmf.servehttp.com server. Trying to access this address from web browser also doesn't work.

Running curl -s http://rmf.servehttp.com/repos.key | sudo apt-key add - returns

gpg: no valid OpenPGP data found.

Likewise, running basic curl to get the key curl http://rmf.servehttp.com/repos.key returns

curl: (7) Failed to connect to rmf.servehttp.com port 80: Connection refused

Therefore sudo apt update has error and when running sudo apt install ... the packages cannot be found.

Any help will be appreciated, thanks!
