I thought this might be related to the krb5 thing, so I created an up to date poudriere jail via pkgbase method and rebuilt all my pkgs, but even then I saw the same thing as Den, that pkg wanted to remove a lot of ports pkgs, as this system is not important I thought I can resolve that after the pkgbase upgrade and started the upgrade.

Florian,

I'm sorry you hit this issue as well, but I feel a bit less crazy now.  At least, about this.  I'm also glad I was able to capture something you weren't.  Long live "gnu screen" being my primary window manager.

I myself had a standby VM from before we converted to pkgbase, so it's a little old, and we might need to re-create a poudriere jail or two, but I'm currently building world as well (pkgbase is in time-out, mister!).  Nothing is lost here, but if any devs would like me to run more commands, or catch more forensics, please let me know.  I suspect this might need to wait for bapt to come back, but I'm not sure.

I'm not trying to get into the recent (ahem) lively discussion thread -- but I am interested in helping solve a problem in any way.  Anyone, free to email me directly, or Paeps has my mobile number and can ping me out of band.  Since I have that other VM, I'm going to leave this VM as-is other than doing a few ls'es to figure out which jails/ports trees I need to re-create.  Sadly, I don't have a snapshot of just before the failure to try to reproduce.
