Create new 'yocto master' project 2. build 'core-image-minimal'. wait until build completes. 3. switch to 'fido' release 4. build 'core-image-minimal' Expected result: Second build should complete successfully. Observed result: Build fails with many(40+) errors similar to: QA Issue: Package version for package libgcc-dbg went backwards which would break package feeds from (0:4.9.3-r0 to 0:4.9.2-r0) [version-going-backwards] Looking further into this, the errors are valid and expected under this particular use case. Suggestions: Either we need to make Toaster recognize this problem in the future and run the "cleanall" command automatically when it is encountered or add a notification clarifying this case in particular and provide an easy way for users to clean the cache - maybe a "Clear cache" button that runs a "cleanall" command in the background? 52433 1 stanciux.mihail 2015-07-16 12:50:16 +0000 Found existing bug 7880 that describes the same underlying issue.
