Comment 7 for bug 392887

Since this blocks user renames for anyone with a PPA, and we (LOSAs) get quite a lot of requests for that we should do one of two things:

- Decide we won't rename anyone's account by any method (even manual workarounds) if they have a PPA
- Fix this bug so they can rename their PPA (with appropriate warnings about implications for PPA breakage)

Currently the workaround which users are often told the LOSAs can do is error prone and cumbersome.
