Bug 771315

Summary: sys-apps/portage-3.0.13: can't calculate dependencies for upgrade from clang-11.0.1 to clang-11.1.0.
Product: Portage Development Reporter: i.Dark_Templar <idarktemplar>

Description i.Dark_Templar 2021-02-18 17:56:31 UTC
Portage can't upgrade clang and other tools from version 11.0.1 to 11.1.0

Reproducible: Always

Steps to Reproduce:
1. emerge llvm, clang, lld 11.0.1
2. emerge qt-creator. I didn't check it with qt-creator from ::gentoo, thus it might be necessary to install qt-creator[clang] from overlay ::dt-overlay-patches and/or unmask and enable clang USE-flag for qt-creator.
3. prepare to upgrade to llvm/clang/lld 11.1.0
Actual Results:  
"emerge -avuDN @world" fails to calculate dependencies

Expected Results:  
"emerge -avuDN @world" should successfully calculate dependencies.

sys-devel/llvm-11.0.1 conflicts with sys-devel/llvm-11.1.0 due to sys-devel/clang-11.0.1 which should be upgraded as well.

$ emerge -pvuDN @world --backtrack=100

These are the packages that would be merged, in order:

!!! The following update(s) have been skipped due to unsatisfied dependencies

I've tried backtrack 0, 30 and 100, result is same as above.
If I try to update only clang/llvm/lld, it fails:
