Trying to install an update to a package failed by the exit code indicated success (i.e., zero). I tried running 'emerge' alone and got an exit code of one (1). I experimented with flags and found that when I used the -u or -U flags I always got a result of zero in spite of the failure. In my case, this makes a script that calls 'emerge' fail to properly determine the result of the attempted update. Reproducible: Always Steps to Reproduce: 1. Find an updated package that will not emerge for some reason. The problem does not arise with a package that has never been installed (such as a masked package). 2. Do: emerge -av <atom>; echo $? 3. Do: emerge -puv <atom>; echo $? You can also use other flags to duplicate the issue, such as -pv and -puv, or nothing at all versus -u by itself. The key to triggering the issue is the -u (or -U) flag. I managed to duplicate the issue on a second server. Actual Results: # LC_ALL=C emerge -av dev-libs/apr-util; echo $?

(details not significant) It may be possible to solve this problem by using package.mask to prevent one of those packages from being selected. However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically. For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook. 1 (this is the expected exit code, since it failed) ------------------------------------- Now try again adding the update flag: # LC_ALL=C emerge -auv dev-libs/apr-util; echo $? * IMPORTANT: 2 news items need reading for repository 'gentoo'. * Use eselect news read to view new items.

Total: 0 packages, Size of downloads: 0 KiB 0 This second test may not be helpful because with the -u flag emerge did not complain that there were no ebuilds, and if that behaviour is correct (I don't know) then the exit code '0' with -u would be appropriate. Expected Results: Exit code indicating failure (e.g., '1') regardless of update flag -u or -U.

Pardon me: In re-reading my report I see what I missed. I focused on the package list and neglected to see that the error message was different with and without the -u. So this is my error in interpreting the messages I was seeing. I'm sorry about the bogus error report. Please close and ignore this with my apology.
