Description Justin Rittenhouse 2020-05-09 12:39:57 UTC

I have a very old system that is fairly out-of-date.  I have been working slowly through updating it.  I finally got it to a point where it would do a merge of some 3-400 packages.  This emerge was taking quite some time, and I have emerge --sync set to run via cron.  The sync removed an ebuild scheduled for merge.

Reproducible: Always

Steps to Reproduce:
1.  emerge --update @world
2.  emerge --sync
3.  Get unlucky and have an ebuild removed via sync while emerge @world is running
Actual Results:  
emerge dies reporting a missing ebuild

Expected Results:  
emerge merges the ebuild because it cached it somewhere

Maybe this is expected behavior, but it seems like Portage would be more robust if it could handle a stupid user deleting ebuilds from under it.

There are some tricks how to upgrade an old system. Please ask on IRC #gentoo or in the forum.
