i'm getting that it cannot find pynac-0.7.6.tar.bz2 from mirrors.

maybe just delay in servers?

i did $ git trac checkout 22838 && make="MAKE -j4" make.

The servers get it only after merge and a new Sage release. Download from github into your upstream directory.

I did some fixes. The most important is the documentation for step was wrong since SR(0).step() == 1. I also changed a little nitpick with alignments. If my changes are good, then positive review.

comment:10

This is conflicting with #22090. I'd rather if you hold back #22090 instead of this. Is it possible?

[tscrim]

comment:11

It seems like Volker has already merged #22090 into his develop branch. So I wouldn't touch #22090. Also, doesn't #22090 expose a regression in pynac?

[rwst]

comment:12

Replying to @tscrim:

Also, doesn't #22090 expose a regression in pynac?

Of course. But I would have liked to be not under time pressure with the fix.

[tscrim]

comment:13

You could mark those failing tests as # known bug for now.

[rwst]

comment:14

I can do that only in #22090 because only there the new file with the test case is introduced. But instead of a new release I'll add a patch here.
