Please do not post screenshots. Instead copy/paste the code and/or
exception (with full traceback - the whole thing) as text between triple
backticks, eg:
```
your code or traceback here
```
This (a) lets everybody see it and (b) lets us copy/paste from it or
quote it in replies for context. Screenshots are not visible to those of
us on email (I visited the web forum, but that is slow and tedious) and
also of little use to the vision impaired. Just something for next time.
Sorry @cameron I’ll remember that for next time and next time I get the error I’ll copy and paste it.
What’s weird also that its only Linux machines affected and not Windows and it’s only 2 machines that mainly does it.
