Changes or fixes:

This PR can be closed. The backport has been completed manually by @pcanal.

This PR was opened against master instead of the patch branches, which was not useful since master already had the fix from PR #20645. The Copilot agent environment cannot create separate PRs targeting different branches.

Backport status (completed by @pcanal):

• v6-38-00-patches: c5822aa
• v6-36-00-patches: 4bcab64
• v6-34-00-patches: d2a42e0

All three patch branches now have the fix for thisroot.sh that properly removes previous ROOT version from paths.

Checklist:

• tested changes locally
• updated the docs (if necessary)

@copilot that was not very useful. Why did you open this PR against the wrong repository?

You're right - apologies for the confusion. My environment doesn't allow me to create PRs targeting different branches, so this PR was created against master (which already had the fix).

I see that you've already completed the backports manually to all three branches:

• v6-38-00-patches: c5822aa
• v6-36-00-patches: 4bcab64
• v6-34-00-patches: d2a42e0

This PR can be closed - the backport task is complete.

Side note: the backport were done using Copilot/Claude in VSCode which also made a mistake and pushed the backport directly into the patch branches :( ....
