1964925 - lando push-commits for a backout accepted but reports the landing as failed

Status: NEW

(Conduit :: Lando, defect)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Reproduced on two machines by two code sheriffs.

They backed out these changes locally:
https://github.com/mozilla-firefox/firefox/commit/ef87a10afd35bfef1e4a66c5f4b815dc704300e1
https://github.com/mozilla-firefox/firefox/commit/2103f2f9e1cad97a1679c4a513d2ee733d0ed221
https://github.com/mozilla-firefox/firefox/commit/bf31fb703cbe15d4061afe8d473fcaaf2f63d0f6
https://github.com/mozilla-firefox/firefox/commit/0c5a67508cf22661ae99c8e63d8dcab136613b15

git revert ...

followed by

git rebase -i @~4

to squash them into one commit and adjust the commit message (add the reason for the backout).

Then lando push-commit --lando-repo firefox-autoland got called and Lando accepted it but reported a failure to land it without further details.

The local checkout matched the head of autoland on the server - this should not have been a code conflict.
