We found a workaround for our migration to Unity. We thought the best solution was to create virtual machines on which to install UCX. Since there are several people on the team, this seemed like the most convenient and scalable solution. The problem occurs after the second installation of UCX on two different workspaces. Basically, with the newly instantiated machine and the installation of UCX on a single workspace, it works. However, when we try to install it on other environments, it gives this error. The solution we found is to create a virtual machine for each environment on which we will install UCX. It doesn't seem like the best solution, but for now it works while we try to understand where the problem lies. Our VM has Ubuntu 24.04 LTS as the operating system.

Hi @antonuzzo96, looks like there are duplicate resource names within the workspace, such as dashboards or widgets, could you please confirm?

[antonuzzo96]

No duplicates of any kind, including dashboards, workflows, widgets, or any other assets.

Issue was resolved in lsql v0.7.4, a ucx dependency: https://github.com/databrickslabs/lsql/releases/tag/v0.7.4
1. Upgrade the Databricks cli: https://github.com/databricks/cli/releases/
2. Upgrade ucx: `databricks labs install ucx`
