Please attach /var/log/apt/term.log. I want to see a former failure recorded in your log file.

In any case, the bug is in dropbox.com's package (version 0.7.1) not in the Ubuntu package (version 0.7.1-2). There's not much that I can do.

[Snoopyski (sgauvin)]

Works now with the last updates... Tks :-)

[Raphaël Hertzog (hertzog)]

Snoopyski, are you sure you're referring to the same problem ? (aka this bug is about the post-removal script failing during upgrade... nothing else).

[Launchpad Janitor (janitor)]

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

(Subscribing David Euresti of Dropbox to this bug since this bug is in the official Dropbox package and not in the Ubuntu one)

I looked into this bug even though it's not in the Ubuntu package. The postrm is failing with exitcode 2. After analysing the postrm, and having made some tries, I believe that it's the "apt-key rm 5044912E" (function uninstall_key) that is failing and returning.

┏(ubuntu-devel-i386) rivendell:~/tmp
┗(511)$ sudo apt-key rm 5044912E
gpg: key "5044912E" not found: eof
gpg: 5044912E: delete key failed: eof
┏(ubuntu-devel-i386) rivendell:~/tmp
┗(512)$ echo $?
2

I would suggest to stop relying on apt-key and instead you should provide a keyring file in /usr/share/keyrings/ and just put a symlink to this file in /etc/apt/trusted.gpg.d/ in the postinst configure (and drop that symlink in the postrm purge). It's cleaner.

Otherwise you should either ignore the failure "apt-key rm" or only call it after having it checked that the key to remove is still in APT's keyring.

[Raphaël Hertzog (hertzog)]

Marking the bug as invalid since it doesn't affect the official ubuntu package.

[Raphaël Hertzog (hertzog)]

It would be nice if someone could confirm my analysis. If you have the problem (and still have version 0.7.1 installed, and not 0.7.1-2), please edit /var/lib/dpkg/info/nautilus-dropbox.postrm to add a "set -x" line just after the first line (i.e. after the line that starts with "#!"). Then run "sudo dpkg -P nautilus-dropbox" in a terminal and paste the output here. Thank you in advance.

Thanks for the report! We will fix it in the next version.
