Service on Ubuntu 20.04.3 not working

[MatthK]

I came across another issue. I tried to install the agent on an Ubuntu server and downloaded the file and installed it with sudo /bin/bash Install_Ubuntu_x64.sh. That worked and didn't seem to come up with any errors. However, in the Home screen, the server does not show up. After a reboot, I checked the agent service to find that there is a Loaded problem (not found) and it also says it failed to connect to the server.

I did a complete reinstall of Ubuntu and just tried to install the remotely-agent again. It does install, and immediately after the install, I can see a lot of files in the directory /usr/local/bin/Remotely/, including the Remotely_agent. However, the service keeps failing with

matth@vs02:~/Downloads$ sudo service remotely-agent status
● remotely-agent.service - The Remotely agent used for remote access.
     Loaded: loaded (/etc/systemd/system/remotely-agent.service; enabled; vendor preset: enabled)
     Active: activating (auto-restart) (Result: exit-code) since Sat 2021-11-20 19:03:02 HKT; 1s ago
    Process: 24567 ExecStart=/usr/local/bin/Remotely/Remotely_Agent (code=exited, status=203/EXEC)
   Main PID: 24567 (code=exited, status=203/EXEC)

When I then check the directory again after a short while, there are only two files left in the directory. They somehow all got deleted.

matth@vs02:~/Downloads$ ls /usr/local/bin/Remotely/ -lia
total 12
 1573611 drwxr-xr-x 2 root root 4096 Nov 20 19:02 .

 1573614 -rw-r--r-- 1 root root    0 Nov 20 19:02 etag.txt

I tried to run the install a few times, but it keeps happening that the files get deleted.

I've observed on a clean installation of Ubuntu 20.04.3:

• Setup script works OK
• First time the agent connects to the server, "systemctl status remotely-agent" shows "New version found" and the setup script runs again.
• After this, either the agent enters a loop where it redownloads and reinstalls the program each time it connects, or it fails to download the zip file and , as the setup script deletes all files before downloading and unzipping, dies.

Same thing happens on CentOS 8. Complete clean install. However I could get it to start with the command dotnet /var/www/remotely/Remotely_Server.dll

The problem on CentOS anyway is that the systemctl file /etc/systemd/system/remotely.service calls /usr/bin/dotnet but the actual location of dotnet bin is /usr/local/bin. Changing the remotely.service file fixes it and I was able to make it work. You could try this on ubuntu.

@saiinformatica I had exactly the same issue. I fixed it by changing http to https in the install script :)

[saiinformatica]

Thank you @lukastrkan for the tip, that worked for me. Checking Redirect to HTTPS on Server Config produces the correct hostname on the script, and probably avoids future client update problems.

Please, this script works on Centos text mode?

@MatthK did you fix it? I have the same problem now with Ubuntu 22.04LTS which should be supported.

Ah, it is probably because this device has ARM64 architecture and the Linux package was x86 / x64. Because if I try this:

odroid@server:/usr/local/bin/Remotely$ ./Remotely_Agent
-bash: ./Remotely_Agent: cannot execute binary file: Exec format error

You can see the error.

No, I never fixed it. As I couldn't find a solution, I gave up and use an RDP connection instead.
