Description Robert Yang 2016-04-12 03:42:18 UTC

I got the following errros when do_fetch failed, the repo exists, but no required 
SRCREV, if it can print that "repo exits, but no SRCREV foo" would help a lot when debugging.

I did a little test, it seems that the fetcher can output some meaningful information as required in this bug.

Please see the error message below.

ERROR: systemd-1_230+gitAUTOINC+1a74d4fc90-r0 do_fetch: Fetcher failure: Unable to find revision 1a74d4fc90cb322a4784a3515bef7118c8f8c5ba in branch master even from upstream

Comment 2 Chen Qi 2016-07-15 06:08:33 UTC

The information in output is correct, thus closing this bug.
