Updating to 11.3U3.1

[smwein]

When I try to update to U3.1 I get the following error.

Error: Traceback (most recent call last):
File "/usr/local/lib/python3.7/site-packages/middlewared/plugins/update.py", line 663, in do_update

raise Exception("Cannot remove file %s" % path)
Exception: Cannot remove file /root/.bashrc

During handling of the above exception, another exception occurred:

Not sure how to to get past this.

Thanks
