I've got a Powermac G4 running debian ppc32.
I've noticed a potential issue with aptitude.
If I run "aptitude update" I notice it never seems to complete.
It'll use 18% or so of my RAM (which is about 450mb I believe) but no
CPU. It isn't swapping.

Strace simply reveals:

[pid 499] futex(0xafefc484, FUTEX_WAIT_PRIVATE, 1, NULL

"apt update" and "apt upgrade" seem to be working fine.

If anyone can assist I would be grateful.

I do not see this problem on my PowerMac G5, however.

Curiouser and curiouser...

with current kernels and everything updated on my PB G4, I tried.
I use aptitude with its curses based interface and always did!
Now, aptitude starts I can update soruces, select packages to upgrade or install, then I hit go and it hangs there forever, never starting
downloads. It used to work.
