Why should portage's autounmask-write feature be expected to resolve blockers? Also: sys-auth/polkit-0.110::local we cannot fix your overlay.
(In reply to Jeroen Roovers from comment #1) > Why should portage's autounmask-write feature be expected to resolve > blockers? I didn't see any real blockers in that output. Or real conflicts. It looks like usual situation when some extra USE-flags required by other package, which is usually handled by autounmask-write. Also, it doesn't clear why these USE-flags was changed after updating to portage-2.2. > Also: > > sys-auth/polkit-0.110::local > > we cannot fix your overlay. It has nothing with this issue: # diff /usr/{,local}/portage/sys-auth/polkit/polkit-0.110.ebuild 60a61 > epatch "${FILESDIR}"/${P}-libjs.patch Only difference is a patch for compatibility with dev-lang/spidermonkey-1.8.7.
Yes, these are automatically resolved. Please provide the complete emerge output.

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.

It doesn't say anything about that you need to unmask anything; so, you could try to raise the backtrack value, it is possible that backtrack happens slightly different with the new release.
(In reply to Tom Wijsman (TomWij) from comment #5) > It doesn't say anything about that you need to unmask anything; so, you > could try to raise the backtrack value, it is possible that backtrack > happens slightly different with the new release. Yeah, you right, --backtrack=13 is minimum value which fix this issue. So, is I have to add this to EMERGE_DEFAULT_OPTS now?
Up to you; higher just means it will take longer, people usually leave it at the default and only increase it temporarily when the output indicates it. It's just a change in the way backtracking works that you're seeing; not sure what they changed, but it causes this case to be less favorable to be resolved and perhaps another case to be more favored. So, pick a sane default that doesn't take to long and perhaps create a shell alias or function that allows you to quickly do the emerge again with a larger backtrack number.
(In reply to Tom Wijsman (TomWij) from comment #7) > Up to you; higher just means it will take longer, people usually leave it at I've benchmarked it, but didn't notice any difference at all - 10, 15 and 30 took exactly same time.
