crash on start "dropbox start -i" Error: [Errno 8] _ssl.c:509: EOF occurred in violation of protocol

[Jerome]

Hi,

I work behind a proxy, using a fresh 13.10 installation of Ubuntu

1) dropbox installed from the main repository does not shown up in the indicator bar.

2) when using the command line "dropbox start -i" i get (deleteing some info):

Starting Dropbox...
Dropbox is the easiest way to share and store your files online. Want to learn more? Head to http://www.dropbox.com/
Error: Trouble connecting to Dropbox servers. Maybe your internet connection is down, or you need to set your http_proxy environment variable.
URL that failed to download: http://www.dropbox.com/download?plat=lnx.x86_64
Error: [Errno 8] _ssl.c:509: EOF occurred in violation of protocol
http_proxy = ***********-https_proxy = ***********
The installation of Dropbox failed.

while "wget http://www.dropbox.com/download?plat=lnx.x86_64" would work fine.

3) Going to the Dropbox website and following the procedure to download and install, i get a finctional dropbox installation in .dropbox

Best regards,

J

Status changed to 'Confirmed' because the bug affects multiple users.

Specifcally, installation fails *even when $http_proxy and/or $https_proxy is configured.

Details:
We have a proxy at 10.32.1.250:8080. It's completely transparent, it simply serves for authentication (log who accesses the internet).

(A) If I do neither configure $http_proxy, nor $http_proxy, I get:

root@ltsp8:~# export http_proxy=
root@ltsp8:~# export https_proxy=
root@ltsp8:~# dropbox start -i

    return self.dict[name.lower()]
KeyError: 'content-length'
The installation of Dropbox failed.

(B) If I configure $http_proxy only, I get:

root@ltsp8:~# export http_proxy=http://10.32.1.250:8080
root@ltsp8:~# export https_proxy=
root@ltsp8:~# dropbox start -i

(at this point, installation hangs forever, obviously trying to get through to an https:// address).

(C) If I configure both $http_proxy and $https_proxy, I get:

root@ltsp8:~# export http_proxy=http://10.32.1.250:8080
root@ltsp8:~# export https_proxy=https://10.32.1.250:8080

So, there's literally no way that works. Dropbox cannot be installed behind a proxy.

Please fix quick!

Please not especially the line
> http_proxy = http://10.32.1.250:8080https_proxy = https://10.32.1.250:8080

This looks as if environments variables for http_proxy and https_proxy get falsely concatenated (programmer forgot a ";" ???)

Looks like just an error in constructing the error message:

def get_download_debug_info(url, e):
    msg = "\nURL that failed to download: %s\nError: %s\n" % (url, e.strerror)
    if "http_proxy" in os.environ:
        msg += "http_proxy = %s" % os.environ["http_proxy"]
    if "https_proxy" in os.environ:
        msg += "https_proxy = %s" % os.environ["https_proxy"]
    return msg

Right, so that's not the cause.
(As an aside, the error messages you get from dropbox are not very helpful. In the first example, you get "KeyError: 'content-length'". In the last example, it suggests setting $http_proxy, while it is already set.)

Content-Length missing suggests that either the proxy isn't functioning properly
(not forwarding the Content-Length header) or that it's returning some status
code that the dropbox installation script doesn't understand.

I'll need to set up a local HTTP proxy to debug this, unless someone offers me a
proxy server that shows this problem. :/

Thanks for caring.
Sorry, I don't have a proxy you can access. If it helps: Ours is Squid with a fairly standard configuration.

Thanks, I'll try reproducing that later.
