    We are also getting the smudge filter lfs failed error when using unity cloud. We moved from a non lfs repo to a lfs one, so maybe that has something to do with it?

    I PM'd SophiaC with Unity, and she changed our project to use an improved LFS pull. It worked much better after that.

    Hey! We have a problem also. For testing purposes we added new file (png tex) to LFS (before that whole project was just in nornal Git repo), since then we are getting an error in Cloud Build that file cannot be read.

    I am falling into a similar situation.
    I noticed that the beginning of the log changed like this.

    After a clean build, it seems that files managed by LFS can no longer be downloaded.
    Is something working on this subject?

    I'm having the same issue!

    update: upon a closer look in my case, the LFS files aren't acutally retrieved... here is a snippet of the log:

    231: [03:42:47] [ INFO]
    232: Cloned in 4 seconds.
    233: GIT: Checkout operation complete.



    The reason is rather obvious, the certificate on my server isn't being used correctly and it also happens locally. (where I had disabled it) In other words, I have to fix my server first ^^

    I doubt that you have the same issue but who knows :)

    I just ran into this same issue quite recently! Here's how I got LFS pulling working:
    1. Before anything else, I had to learn that there's a difference between a deploy SSH key (the "read-only access key" in your build log) and a user authorization SSH key. If you use a deploy SSH key to grant Unity Cloud Build access to your repo, it won't pull LFS files. You'll have to generate a new SSH key and use it to authorize a new user.
    2. Create a new Bitbucket user with read-only access to all your repos for Unity Cloud Build. This new Bitbucket account is your machine user. Unity Cloud Build will log in as this machine user and check out your repos that way. (In theory you can let Unity Cloud Build log in as your own account, but that creates all sorts of security compromises)
    3. Refresh your Unity Organization SSH key. The only way to do this is through the Unity Cloud Build API. If you've never used the API before, sorry. And good luck. Remember, this step invalidates your old SSH key, so until your Machine User is up and running, none of your Unity Cloud Build projects will be able to check out code.
    4. While logged in as your Machine User in Bitbucket, go to "User Settings > Security > SSH Keys" and add your new SSH key here. Do not use your new SSH key as a deploy key.
    I think that's all it takes. Next time you start a Cloud Build, the server will use the SSH key to log in as your machine user, check out the latest commit from your repo (LFS files and all!), and build as normal.

    This is seriously hampering our cloud build operations also, as builds that were working before suddenly aren't.. such a pain!

    Thanks for the tips! I'll probably give this a shot in the next week or two and report my findings.

    How do I connect Unity Cloud Build to a Bitbucket repository using LFS?

    Access and Cloning works, but LFS files are not checked out before the build.
    The build log shows:

    The linked documentation page by atlassian excplicitly states :

    But Unity Cloud build is set up to access the repo with an access key and I don't see an alternative.
    [edit] Or even a way to change this after the fact?

    [2nd edit]
    Ok now I understood the proposed workaround from 3 posts earlier. But unless I want (or even can) add a dummy User to bitbucket for this access I'm stranded...
    That is, until bitbucket get's it together and supports LFS checkout with ssh keys or until Unity Cloud Build can access bitbucket with an App Password.

    Still no workaround to get Visual Studio Online LFS and Unity Cloud Build to work together?
