Created attachment 662164 [details] emerge info emerge update cannot proceed due to slot conflict. I'm a bit confused because each listed package (dev-libs/libclangformat-ide-10.0.0:10/10::gentoo, sys-devel/llvm-10.0.1:10/10::gentoo, sys-devel/clang-10.0.1:10/10::gentoo) can be merged seperately. During this slot conflict issue, what do the ^^^^ arrows represent. I have not been able to figure out the cause but now I cannot update my system. Output below: sudo emerge --update --newuse --deep --with-bdeps=y @world -a --keep-going --changed-deps --changed-use -v --verbose-conflicts These are the packages that would be merged, in order: Calculating dependencies ... done! !!! Multiple package instances within a single package slot have been pulled !!! into the dependency graph, resulting in a slot conflict: sys-devel/llvm:10 (sys-devel/llvm-10.0.1:10/10::gentoo, installed) USE="libffi ncurses xml -debug -doc -exegesis -gold -libedit -test -xar -z3" ABI_X86="32 (64) (-x32)" LLVM_TARGETS="AMDGPU BPF NVPTX (X86) -AArch64 -ARC -ARM -AVR -Hexagon -Lanai -MSP430 -Mips -PowerPC -RISCV -Sparc -SystemZ -WebAssembly -XCore" pulled in by ~sys-devel/llvm-10.0.1:10/10=[-debug,llvm_targets_AMDGPU,llvm_targets_BPF,llvm_targets_NVPTX,llvm_targets_X86,abi_x86_32(-),abi_x86_64(-)] required by (sys-devel/clang-10.0.1:10/10::gentoo, installed) USE="static-analyzer xml -debug -default-compiler-rt -default-libcxx -default-lld -doc -test" ABI_X86="32 (64) (-x32)" LLVM_TARGETS="AMDGPU BPF NVPTX (X86) -AArch64 -ARC -ARM -AVR -Hexagon -Lanai -MSP430 -Mips -PowerPC -RISCV -Sparc -SystemZ -WebAssembly -XCore" PYTHON_SINGLE_TARGET="python3_6 -python3_7 -python3_8 (-python3_9)" ^ ^^^^^^^^^^^^^ ~sys-devel/llvm-10.0.1:10=[debug=,llvm_targets_AArch64?,llvm_targets_AMDGPU?,llvm_targets_ARM?,llvm_targets_BPF?,llvm_targets_Hexagon?,llvm_targets_Lanai?,llvm_targets_Mips?,llvm_targets_MSP430?,llvm_targets_NVPTX?,llvm_targets_PowerPC?,llvm_targets_RISCV?,llvm_targets_Sparc?,llvm_targets_SystemZ?,llvm_targets_WebAssembly?,llvm_targets_X86?,llvm_targets_XCore?,llvm_targets_ARC?,llvm_targets_AVR?,abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_s390_32(-)?,abi_s390_64(-)?] required by (sys-devel/clang-10.0.1:10/10::gentoo, installed) USE="static-analyzer xml -debug -default-compiler-rt -default-libcxx -default-lld -doc -test" ABI_X86="32 (64) (-x32)" LLVM_TARGETS="AMDGPU BPF NVPTX (X86) -AArch64 -ARC -ARM -AVR -Hexagon -Lanai -MSP430 -Mips -PowerPC -RISCV -Sparc -SystemZ -WebAssembly -XCore" PYTHON_SINGLE_TARGET="python3_6 -python3_7 -python3_8 (-python3_9)" ^ ^^^^^^^^^^ (sys-devel/llvm-10.0.0:10/10::gentoo, ebuild scheduled for merge) USE="libffi ncurses xml -debug -doc -exegesis -gold -libedit -test -xar -z3" ABI_X86="32 (64) (-x32)" LLVM_TARGETS="AMDGPU BPF NVPTX (X86) -AArch64 -ARC -ARM -AVR -Hexagon -Lanai -MSP430 -Mips -PowerPC -RISCV -Sparc -SystemZ -WebAssembly -XCore" pulled in by ~sys-devel/llvm-10.0.0:10/10=[-debug] required by (dev-libs/libclangformat-ide-10.0.0:10/10::gentoo, installed) USE="-debug" ABI_X86="(64)" ^ ^^^^^^^^^^^^^ ~sys-devel/llvm-10.0.0:10=[debug=] required by (dev-libs/libclangformat-ide-10.0.0:10/10::gentoo, installed) USE="-debug" ABI_X86="(64)" ^ ^^^^^^^^^^ 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.
