Problems uploading package to launchpad due to "checksum mismatch" error

Question

I'm having a lot of problems uploading my showdown project to a PPA.

I've setup correctly PGP keys and my public ssh key to launchpad. I've packaged with debuild my C++ project, producing a source package lintian gave me only those two warnings that I think are ok for the showdown rules:

W: massren source: native-package-with-dash-version
W: massren source: binary-nmu-debian-revision-in-source 1.0-0extras12.04.1~ppa2

Producing a binary package works to and the package installs without problem on my ubuntu 12.04 machine, I only have a few more lintian warnings about the fact I'm installing in /opt/extras.ubuntu.com/

I'm uploading with:

dput ppa:gabrielegreco/massren massren_1.0-0extras12.04.1~ppa2_source.changes

When I upload with dput I have no errors, signatures seems ok, and public key seems accepted to (since the upload goes on without asking passwords...):

  Uploading massren_1.0-0extras12.04.1~ppa2_source.changes: done.
Successfully uploaded packages.

At the moment I'm not receiving responses from launchpad site, but the upload does not show in the ppa page.

Previous attempts gave me response e-mails with different kind of errors:

File massren_1.0-0extras12.04.1~ppa1.tar.gz mentioned in the changes has a checksum mismatch. 1503fa155226cbc4aba2f8ba9aa11a75 != 294a5e0caf3fe95b0b007a10766e9672
File massren_1.0-0extras12.04.1~ppa1.tar.gz mentioned in the changes has a checksum mismatch. 1503fa155226cbc4aba2f8ba9aa11a75 != 294a5e0caf3fe95b0b007a10766e9672

Or more cryptic:

GPG verification of /srv/launchpad.net/ppa-queue/incoming/upload-ftp-20120629-163320-001135/~gabrielegreco/massren/ubuntu/massren_1.0-0extras12.04.1~ppa1.dsc failed: Verification failed 3 times: ["(7, 58, u'No data')", "(7, 58, u'No data')", "(7, 58, u'No data')"]
Further error processing not possible because of a critical previous error.

Any idea how can I solve this problem? I'm new to ubuntu packaging, so I may miss some step... There is an alternative to dput (aka manual upload)?

Answer 1

It seems the problem was in the untangle firewall that is between me and launchpad. I've uploaded the files by hand at home and sent them through FTP to launchpad.

I used the command line "ftp" client since I cannot use "dput" on OSX and ncftp did not worked (maybe because it didn't set the correct email as password of the anonymous user)?

Anyway this is the sequence to do to upload manually:

• Connect with FTP to ppa.launchpad.net
• Use anonymous as user
• Use the mail address you used to register to launchpad as password
• change directory to ~yourlaunchpadusername/yourppa/ubuntu
• upload the files packagename_version.dsc, packagename_version.tar.gz, packagename_version_source.changes
• exit FTP and wait for email confirmation.

If your build doesn't complete correctly (in my case the problem was an unmet dependency) you have to upload the files with a different version or you'll get an error (I changed ~ppa2 to ~ppa3 in the end).

Answer 2

Open ~/.dput.cf in a text editor and add this text:

[your-ppa]
fqdn = ppa.launchpad.net
method = ftp
incoming = ~<your_launchpad_id>/<ppa_name>/ubuntu/
login = your_launchpad_id

allow_unsigned_uploads = 0

Save the file, quit the text editor, and run:

dput your-ppa *_source.changes
