Build pipeline does not delete
If you have deleted the release in question, but you still get this error, the solve for it is:
- Go to the build pipeline in question.
- Under the 'Runs' tab, open each "run" individually
- If a run is being retained, you'll see a white box at the top with verbiage like "This run has been retained forever by 82 (Pipeline)" and to right, you'll see a button "View Retention Releases". That's where you'll delete the one or more retention releases.
- You'll have to go through each "run" and repeat this process
If that white box/button isn't visible, that particular run isn't retained. You can confirm so by clicking the three dots in the top right corner and selecting "view retention releases"
I was having the same problem and tried different browsers, platforms etc. I found that by removing each release manually under the releases tab, going back to build and then trying to delete the pipeline again worked for me.
