When I started mathematica, this message popped up.

Part::partw: Part 5 of PacletManager`Utils`Private`$taskData[2] does not exist.

Does anyone know what this is? My version is mma 11.2.

  • $\begingroup$ Have you ever explicitly interacted with the paclet manager, in any manner? $\endgroup$ – Szabolcs Oct 24 '17 at 12:20
  • $\begingroup$ No but I installed some packages I don't know if they did. But things were fine when I was using mma 11.1. $\endgroup$ – Turgon Oct 24 '17 at 13:40
  • $\begingroup$ What packages did you install, and how exactly did you do it? $\endgroup$ – Szabolcs Oct 24 '17 at 13:47
  • $\begingroup$ I installed FeynCalc, FormLink, CollierLink, X, FeynHelper, FIRE, LoopTools, Litered, CARONICA, and mostly I just put them in the Applications folder but some of them requires more and I just follow the instruction and use the auto-install script. Beyond that I did nothing related to paclet manager. $\endgroup$ – Turgon Oct 24 '17 at 14:10
  • $\begingroup$ I see the same warning message on the save version. Started a few days ago. The only "special" actions that I have taken are Needs["AuthorTools`"] NotebookRestore[] $\endgroup$ – user6546 Nov 3 '17 at 19:36

We believe this should be fixed in Mathematica 12.0. We were never able to reproduce this internally so we're not completely sure about this, though. Please let us know if this continues to happen in 12.0 for you.
