ValueError: too many values to unpack

[viral32111]

Hey, I am getting the following error after attempting to run sudo apt-offline get --bundle bundle.zip apt-offline.sig on the online system:

Fetching APT Data

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/apt_offline_core/AptOfflineCoreLib.py", line 864, in stripper
    url, localFile, size, checksum = item.split(' ')
ValueError: too many values to unpack (expected 4)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/apt-offline", line 28, in <module>
    main()
  File "/usr/lib/python3/dist-packages/apt_offline_core/AptOfflineCoreLib.py", line 2503, in main
    args.func(args)
  File "/usr/lib/python3/dist-packages/apt_offline_core/AptOfflineCoreLib.py", line 1253, in fetcher
    (ItemURL, ItemFile, ItemSize, ItemChecksum) = stripper(item)
  File "/usr/lib/python3/dist-packages/apt_offline_core/AptOfflineCoreLib.py", line 868, in stripper
    url, localFile, size = item.split(' ')
ValueError: too many values to unpack (expected 3)

The apt-offline.sig was generated on the offline system using sudo apt-offline set --upgrade apt-offline.sig.

I'm running Ubuntu 22.04.1 on both systems, and using version 1.8.5 of this package.

This appears to be caused by this Ubuntu bug: https://bugs.launchpad.net/ubuntu/+source/ubuntu-advantage-tools/+bug/1992026

I was able to work around it by following the recommendation to remove /etc/apt/apt.conf.d/20apt-esm-hook.conf on my offline machine.

That seems to be right as I've just inspected the contents of the apt-offline.sig file and it indeed contains a message about Ubuntu Pro:

Try Ubuntu Pro beta with a free personal subscription on up to 5 machines.

Removing that file does indeed stop this message from being written to the file, thanks!

Fixed this and created a pull request.

@kyp44 I see that you closed the PR. Is this still a valid issue ? Otherwise, please close this issue.

We did have another similar issue originating from Ubuntu, where the apt output was appended with extra text garbage. I believe that was fixed in one of the previous releases.

I believe this was actually fixed in apt itself, in that they no longer print the offending message when you run it in silent mode like apt-offline does. Like somebody on that development realized, "hey we definitely shouldn't print this message if we're in silent mode".

Thanks. I still adapted your proposed change because we needed more checks in place for the generated signature file; given that apt-offline caters to many Debian derivatives too.
