Thanks, I've synced this to Ubuntu but unfortunately it's failing on the
newly-added arch-specific tests for NDBM:

autopkgtest [11:12:06]: test ndbm: [-----------------------
testing NDBM reading...
buster-ndbm OK
opening NDBM file failed: No such file or directory at -e line 1.
autopkgtest [11:12:06]: test ndbm: -----------------------]
ndbm                 FAIL non-zero exit status 1
autopkgtest [11:12:07]: test ndbm:  - - - - - - - - - - results - - - - - - - - - -
autopkgtest [11:12:07]: test ndbm:  - - - - - - - - - - stderr - - - - - - - - - -
opening NDBM file failed: No such file or directory at -e line 1.

So this is currently blocked in disco-proposed.
