**Issue** When a file lock prevents an MR being merged, there are two issues: 1. The **Merge** button is available when it's not possible to merge the MR. 1. The associated message is misleading. The current message is as follows:  There are several issues with this message: 1. It suggests that the issue is temporary, and that retrying the merge will correct the situation. If I understand correctly, only removing the file's lock will correct the situation, allowing the MR to be merged. 1. The message starts `Something went wrong...`, indicating the cause of the failure is not certain. In fact the cause is known, and details are provided. 1. In this instance it's not entirely clear that `Gadoo Gadah` is a GitLab user's name. **Suggestion** 1. Don't show the **Merge** button when a file contained in the MR is locked. 1. Improve the associated message, perhaps: > Merge request cannot be merged because file <filename> is locked. Check if the file's lock can be removed and if so, try the merge again.
