What is backtracking and how can I have a slot conflict if it's the developers who determine what version sits in a slot? Backtracking refers to how the dependency resolver works - it couldn't figure out a way to satisfy your requirements. You have a slot conflict because two different packages that you asked for require two different versions of setuptools to be installed at the same time in the same slot, or at least that is what portage interprets what it is finding. The verbose output (attached) says that the package with /"new SLOT installation (side-by-side versions)" /is: dev-lang/python-3.6.5:3.6/3.6m The version in /var/db/pkg/dev-lang/python-* is: /var/db/pkg/dev-lang/python-3.5.4-r1/python-3.5.4-r1.ebuild:SLOT="3.5/3.5m" That doesn't look like the same slot... How can there be a slot collision? If the developers say, slot 3 is for a particular version, why should anybody want to push anything else into slot 3? I'd need to see more of the output to get a sense of what is actually going on - posting 10 lines out of what was probably 1000+ lines of output honestly doesn't help anybody to assist you. Yes, the whole output is tedious but probably contains clues. Gladly! I've attached the output of this command: sudo emerge --verbose y --verbose-conflicts --verbose-slot-rebuilds --oneshot portage 2>&1 | tee emerge-portage-2.txt I presume that the flags in front of the dependency list are those given in the --pretend option of emerge(1) ... One might say, I have a package already dependent on setuptools and it's not the right one, but how can it be that two different versions want to go into the same slot? There are many ways this can happen. Maybe package A wants setuptools 40.7.3 or greater, and package B wants setuptools 40.6.3 or lesser, and you asked for both. But isn't that exactly what slots are supposed to address? How can there be a conflict? A limited number of slots? Often though it is an issue with not backtracking enough - if you're doing a huge update often you need to add --backtrack=100 or rarely even a larger value in order for portage to find a way to meet the requirements. Can I follow the backtracking in this attached output somehow, to see what how backtracking works? Sometimes you need to include --with-bdeps=y because something portage isn't considering in-scope is pulling in something that conflicts, and it could be resolved by letting portage update more packages. Backtracking is something to do with dependency checking. I haven't seen any explanation of what goes on in dependency checking and why backtracking is necessary. Can someone point to an explanation? Basically your config files, like the world file, and the profile system set, contain a list of stuff you want. Portage wants to give you want you want. Maybe these files specify 200 packages you're interested in directly. Each of these might ask for 5 more, and each of those 5 more, and so on. Portage works backwards through the dependency tree to generate a list of every requirement of every package. These can form circular loops, and the tree can get quite large very quickly. As an optimization I believe portage avoids traversing the entire thing and only goes back so far - usually it can find a solution to your requirements without traversing the entire tree. I'm trying to understand that ... A -> + | + -> B ->+ || |+ -> C[0] |+ -> D | + -> C[1] Okay, so backtracking is ... when I'm at C[1] and see there's already a C[0] ... Then I go back to B to see if it might be happy with C[1]? !!! Your current profile is deprecated and not supported anymore. !!! Use eselect profile to
