[m-users.] I'm back and I need help!

[Fabrice Nicol]

If you are comfortable with using Docker there is also a working ROTD image
dating back from about a month. It is normally updated daily to current
ROTD.

https://github.com/fabnicol/ubuntu4mercury

You can use this image to possibly bootstrap a build from recent source
code, should you meet problems doing so directly (this has been recently
tested).

NB: For about a month the GitHub Actions process has been failing owing to
memory overload. I will have to streamline the build a little for it
continue working.
