I am trying to follow this link instructions https://urbackup.atlassian.net/wiki/display/US/Download+custom+client+installer+via+Python

but when I run the script I get [quote=""]custom client installer via Python[/quote] I have tested the user and I am able to login with that user from the web gui I maybe missing something in the script

Should this be correct?

[quote=“tjohnson1989”]I am trying to follow this link instructions https://urbackup.atlassian.net/wiki/display/US/Download+custom+client+installer+via+Python

but when I run the script I get [quote=""]custom client installer via Python[/quote] [/quote]

Is this the output? How are you running the script?

3

I have python installed on my windows 8.1 and I am trying to run it through commandline.

This python script works great for windows, but I’d like to adjust it to work with Macs. It looks like it would rather easy, just download the Mac script instead of the Windows EXE at the end, but how would you do that? Thanks.

I’m thinking if somehow this was set to run at the end of the python script, would do the trick, replacing the downloading and running of the exe …

TF=mktemp && curl “https://server/x?a=download_client&lang=en&clientid=client_id&authkey=auth_key&os=mac” > $TF && bash $TF; rm $TF

Close. You’ll have to add "os": "mac" to download_file. And probably start it with sh installer.

thanks, here’s what you have to modify to make it a macos silent installer…

    if "already_exists" in new_client:
    print("Client already exists")
     
    status = get_json("status")
     
    if "client_downloads" in status:
        for client in status["client_downloads"]:        
            if (client["name"] == clientname):
                print("Downloading Installer...")
                 
                if not download_file("download_client", "ClientInstaller.sh",
                             {"clientid": client["id"], 
                             "os": "mac" }):
                    print("Downloading client failed")
                    exit(1)
    else:       
        print("Client already exists and login user has probably no right to access existing clients")
        exit(2)
else:
    if not "new_authkey" in new_client:
        print("Error creating new client")
        exit(3)
         
    print("Downloading Installer...")
              
    if not download_file("download_client", "ClientInstaller.sh",
                         {"clientid": new_client["new_clientid"],
                          "authkey": new_client["new_authkey"], 
                          "os": "mac"
                          }):
          
        print("Downloading client failed")
        exit(1)
      
print("Sucessfully downloaded client")
os.system('sh ClientInstaller.sh -- silent')
exit(0)

By the way, what rights does the account need? According the the script…

“status”: “some”
“add_client”: “all”
Optionally, to be able to install existing clients:
“settings”: “all”

But if you look at the urbackup manual, there is no add_client
