Hi libgc maintainers,
Can you please comment? We missed the 10.10 point release already and
10.11 may happen after we release bullseye, but at least we could
improve the upgrade for people upgrading after 10.11. Do you agree with
me doing an NMU to fix this issue?
I've been running my local piuparts buster->bullseye upgrade tests with
the attached patch applied to src:libgc in buster. Except for some
corner cases this has resolved the majority of the upgrade paths where
the circular Conflicts previously prevented libgc1 and guile-X.Y-libs
to be upgraded.
