Comment (by mkoeppe):

 The recent sage-logger changes from #20640 seem to cause a minor problem.

 When installing an "experimental" package, Sage warns a lot and then
 prompts the user.
 Because of line buffering, one does not see the prompt, but Sage just
 waits indefinitely.

 {{{
 sage -f latte_int
 ...
 [latte_int-1.7.3] =========================== WARNING
 ===========================
 [latte_int-1.7.3] You are about to download and install an experimental
 package.
 [latte_int-1.7.3] This probably won't work at all for you! There is no
 guarantee
 [latte_int-1.7.3] that it will build correctly, or behave as expected.
 [latte_int-1.7.3] Use at your own risk!
 [latte_int-1.7.3]
 ===============================================================
 }}}
 <--- This is where it asks "[latte_int-1.7.3] Are you sure you want to
 continue [Y/n]?" but this is line-buffered and not visible to the user.
