! Package scrbase Error: unknown option `pagenumberwidth=2.1em'.

[tbm]

I get the following error after updating kaobook:

! Package scrbase Error: unknown option `pagenumberwidth=2.1em'.

The change was made in 2048120ec12eda29.

Maybe my scrbase is too old? (I'm on Debian 10/stable)

I am having the same issue (also on Debian 10/stable), and yes it does appear that an old version of scrbase is the problem. scrbase is part of KOMA-Script (which this project uses), and texdoc koma-script (or more specifically, texdoc scrguien) on Debian shows the version as 3.25. Searching for pagenumberwidth there gives no results, but the latest documentation, linked from the CTAN page, tells me it's there; but only from version 3.27.

I don't know enough about TeX programming to fix this issue myself, and Debian (and any others still using the old code) may upgrade their version after a while anyway, but it would be nice if some conditional code to check for this feature could be added in the meantime...

You are right, I have now added a check so that the pagenumberwidth option is used only if scrbase is at least version 3.27. Could you please confirm that now there are no errors? Thank you.

Now I get:

! Undefined control sequence.

?

If I revert b3f57c979cc42ac4b it works.

[fmarotta]

I have added a version check for that as well.

Thanks it works now!
