wstool failing with tf2_msgs

Note this is similar, but not identical to this question - the other question was when repositories had been renamed; this looks like a GitHub release process bug, perhaps?

I'm using rosinstall_generator to create a list of modules to feed into wstool, and the lines include:

- tar:
    local-name: geometry2/tf2_msgs
    uri: https://github.com/ros-gbp/geometry2-release/archive/release/kinetic/tf2_msgs/0.5.20-0.tar.gz
    version: geometry2-release-release-kinetic-tf2_msgs-0.5.20-0

This gives an error:

ERROR [vcstools] Tarball download unpack failed: "geometry2-release-release-kinetic-tf2_msgs-0.5.20-0 is not a subdirectory with contents in members ['geometry2-release-release-kinetic-tf2_msgs']"[/vcstools]

Directly downloading the URL from GitHub, I see that unlike other projects, the tarball has the directory geometry2-release-release-kinetic-tf2_msgs without any version number.

Other packages like tf2_eigen, tf2_geometry_msgs bond_core/smclib and image_common/calibration_parsers fail for identical reasons.

Of course, editing the version with something like this works:

sed -i 's/version: \(geometry2-release-release-kinetic-tf2_msgs\)-[0-9\.\-]\+/version: \1/g' input_file.txt

However, is there a neater workaround, or can the GitHub end be fixed?

UPDATE: I've had a go at fixing the source; see my GitHub fork.

You're running into (something similar to) ros/geometry2#306. We ran into that as well in robust-rosin/robust#69, but only when trying to fetch old releases.

I'm curious: are you trying to build ..

.. an old checkout of tf2 packages?

As to a fix: see the comments on ros/geometry2#306. I believe that summarises it quite well.

Yes, I've seen these conversations, but I think mine is different as rather than a renamed base name, my problem is a missing version number. I'm just doing rosinstall_generator --rosdistro kinetic --from-path my_project --deps --exclude opencv" +wstool init` basically.

You're correct, I'd read your question too hastily.

Perhaps Github has changed something recently? This might warrant an issue on the wstool issue tracker? If you do post there, could you please post a comment with a link to your issue here? Just so we keep things connected.

I've reported it here: vcstools/wstool#130.

Already commented on the PR you submitted, but just for completeness: the proposed changes are a work-around, not a fix. The problem is with GH: either they've change something in their API/backend and haven't communicated ..

.. that, or they've introduced a regression and should fix it.

Until we know which it is, we can't really fix anything in wstool.
