aptitude downloads where apt, apt-get or synaptic hang

[cupakm]

Hi all,

I can't figure out why apt or apt-get (seemingly) randomly hang on downloading packages - happened multiple times, no matter the repo component (main / contrib / non-free),
two samples:

Letting it download again results in a hangup at the same %. Apt-get or synaptic behave likewise.
Clean, autoclean, or computer restart do help - sometimes, can't figure out when.

Strangely, aptitude does work:

Is something being left misconfigured?

not sure why it is stalling so cant help you there.

having stretch and buster in your sources.list is not good.

[cupakm]

Ok, commented out stretch, but I guess that does not affect the stalls.

[Head_on_a_Stick]

commented out stretch

That's a bit like applying a tourniquet after the patient has already died of exsanguination

You need to reinstall from scratch, you have broken your system.

You can likely escape the reinstall. What is it, stretch or buster - not what you want, but what it thinks. Change distro or source list and make them match. Review apt logs for clues to where it's getting confused...Drop to VT1 and kill LM's DM's, xorg and the like. Fire up aptitude and explore, and remove anything broken. Then install what you need from a single repository. Then restart and proceed to re-complicate the system with synaptic...If apt logs show a clear issue you could skip all the VT safety and use synaptic directly...To be clear, something needs to be removed before you proceed.

Hi there. I can't simulate it any more - hangs went away. Don't know why they occurred, nor why they disappeared.
And that before I've cleaned up the buster/stretch repo mix. There also were no broken packages (at least nothing popped that error message).
