    Hi there,
    I have just downloaded 2019.3.5f1 and I wanted to add Entities package to a new project. This is what I have got as an error message in Console:

    Cannot perform upm operation: EBUSY: resource busy or locked, open '-----\Library\PackageCache\.tmp6760amsihKOTPeMr\copy\Unity.Entities\ConverterVersionAttribute.cs' [NotFound]
    UnityEditor.EditorApplication:Internal_CallUpdateFunctions()
    Error adding package: com.unity.entities@0.6.0-preview.24.
    UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

    Let me know how to fix it.

    Hello,

    Sorry to see that you are having this issue. Could you please include the editor logs. It could be some kind of permission issue on the folder. Maybe a super eager antivirus removing the files?

    If you try in other Unity versions do you have this problem?

    Cheers,

    Supi

    I had the same issue recently. Simply go to the folder location specified, open the folder properties window and make sure to have Read Only unchecked so that Unity could have read/write access to that directory. Hope this helps!

    Mine was due to having VS Code open for editing my scripts. Once I closed that, it solved my issue.

    Same issue, happens a LOT. And theres usually no way to move forward, you can try removing your library folder etc reimporting everything. Been seeing this for ages now! Unity need to actually solve these type of issues asap, essentially they brick the whole damn package manager, and in extension the whole engine.

    Closing VSCode fixed this for me, too...and that disturbs me. Why is VSCode locking files that I'm not even opening?

    It seems to try to be smart behind the scenes to facilitate code completion, "go to definition," and other features. It probably has to open a lot of files to maintain that sort of context.

    Hey. For anyone that's running into this issue when vscode is closed, I found a much more insidious culprit.

    The git integrated filesystem monitor.

    I, for example, was getting the error:
    [Package Manager Window] EBUSY: resource busy or locked, rmdir 'C:\ProjectPath\Library\PackageCache\.tmp19804vubalWIte5Cz\clone'
    
UnityEditor.EditorApplication:Internal_CallUpdateFunctions ()


    After looking at task manager I saw that there were a bunch of git instances that unity was creating and were getting stuck with the cmd-line arguments: `fsmonitor--daemon run`

    This is because when I installed Git, I activated the (experimental) integrated filesystem watcher.

    You can disable it by going to 
    C:\Program Files\Git\etc\gitconfig
    and setting

    useBuiltinFSMonitor = false


    ....

    I need to stop enabling experimental features

    Thanks for the advice. I couldn't imagine VS Code has something to do with it.

    I struggled for ages until I found this post and had the issue resolved by closing VSCode.

    Since VSCode does not seem to be the only culprit, it might be an idea for Unity to alleviate the problem by adding a tiny loop around the file opening code that retries for a few times. This would at least reduce the number of sporadic failures caused by other programs scanning the directory.

    Another fun case; my project was located in a Dropbox folder, where a sync issue was causing this error. Pausing sync resolved it (or moving the project out of Dropbox of course).

    I'm pretty sure Unity should still implement a fix for this. VSCode and git's filesystem watcher don't permanently lock files, do they? I bet Unity needs to implement some retry and backoff to avoid this issue. Unity probably tries to do too much too fast without any retry logic.

    Unity copies the package files to a temporary staging folder next to the final location, then renames the staging folder to the package name. This makes the installation "atomic", i.e. either the package is present and complete, or it's not; you will never have a package with some files missing due to interrupting the process, for instance. (That doesn't really seem doing "too much too fast", but you're right, there should be some safety mechanism, and we're looking into that issue.)

    Unfortunately, the problem, as I understand it, is that VS Code's file watcher immediately detects the new files are added in this staging folder and immediately opens them for reading the contents, probably to build some metadata cache and/or IntelliSense db. During that time, it's not possible to rename one of the ancestor folders. If a package contains a lot of files, the folder will therefore remain "un-renamable" because of a VS Code for a longer time, and this increases the likelihood of Unity failing to rename the folder. A typical "race condition", if you will.

    The same probably happens with other software like OneDrive and Dropbox, for instance. And to be fair, it might not be VS Code itself that's the problem, but one (or more) of the extensions loaded in it (including third-party extensions). The simple workaround for now is to close VS Code (or whatever software is eagerly opening and locking files) before opening/creating a project. Another workaround might be (disclaimer: I haven't tried it) to make the problematic VS Code extensions ignore folders with a '.' prefix, if that is possible for those extensions.
