Uploading to PPA fails, showing "[Errno 111] Connection refused"

Is there a firewall between you and the greater internet?

I can access PPA archives through http, that is to say, I can get on http://ppa.launchpad.net/ .
But I am not able to access ppa.lauchpad.net through ftp, which is necessary for uploading.

Yes, so I'm wondering if there is a firewall that may be blocking your FTP access via port 23.

How to check this?

Hi Cheese,

I'd try to access ftp with user anonymous and empty password to see if you can reach the server.

ursula@phoenix: ~ $ ftp ppa.launchpad.net
Connected to ppa.launchpad.net.
220 0.0.0.0 Canonical FTP server ready.
Name (ppa.launchpad.net:ursula): anonymous
331 Password required
Password:
230 Login Successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> bye
221 Goodbye.

See if this helps.

Thanks,

Úrsula

I can work through this procedure.

cheese@cheese-laptop:~$ ftp ppa.launchpad.net
Connected to ppa.launchpad.net.
220 0.0.0.0 Canonical FTP server ready.
Name (ppa.launchpad.net:cheese): anonymous

221 Goodbye.

But it still show "[Errno 111] Connection refused" when I upload with dput.

cheese@cheese-laptop:~$ cat .dput.cf
[my-ppa]
fqdn = ppa.launchpad.net
method = ftp
incoming = ~cheeselee/ppa/ubuntu/
login = anonymous
allow_unsigned_uploads = 0

Since you can ftp directly to ppa.launchpad.net it indicates that there is no problem with your connection or our servers.

I suspect that you have a proxy configured somewhere and it's refusing connections for whatever reason.

Can you try adding this to your .dput.cf:

passive_ftp = 0

I added the line. But now it turn to another situation.
dput is frozen after showing this:

rejected by the upload queue management software.
Uploading to my-ppa (via ftp to ppa.launchpad.net):

Then the command prompt doesn't show back and there is a dput process but no ftp one.

Ok then that didn't work.

As far as I can see, you've got a local problem and I'm not sure what else we can do to help here.

Doing something like:
dput my-ppa mentohust_0.2.5-0~r1_source.changes; netstat -an|grep 21

This will show the ftp session closing down and you can double check where it went.

After running dput my-ppa mentohust_0.2.5-0~r1_source.changes; netstat -an|grep 21 , it shows something like this after the messages from dput:

What can I find out from the above informations?

The line:

tcp 0 1 192.168.14.127:45972 91.189.90.217:21 FIN_WAIT1

Means that dput tried to connect to ppa.launchpad.net and that you're not getting proxied.

I have no idea what can be wrong since you can connect with ftp directly. It is still a local problem and not a Launchpad problem. As such the only thing I can recommend is asking on #ubuntu-motu or the forums.

As a work-around, you can actually use ftp instead of dput for now.

Did anyone find a solution to this?
