zypper enhance disk/download space checks

[paigeadelethompson]

zypper dup anticipates final diskspace usage, as well as the amount of diskspace available but attempts to download more packages than it has disk space available for. It doesn't warn you of that or anything pre-flight it just presents you some facts about how much disk will be used how much total, etc. Wouldn't it be better if there were a failure mode or some kind of indication as to whether or not the operation can complete ?

I will later attempt to remediate by relocating the newly downloaded RPMS to my home dir. Just thought I might throw this out there though I honestly couldn't even figure out why I'm being forced to update to a different version (15.1) suffice to say I'm a little bit annoyed at this point. I did check around a bit to see if there was any obvious reason (turned off all of my 3rd party repos, etc) for being forced to upgrade from 15.1 but just couldn't find it, fwiw. This operation became imparitive anyway after I installed a package (as I normally would when I need something) and several shared libraries were replaced causing missing linked symbols errors in some programs, also far from an ideal experience

[paigeadelethompson]

I don't mean to sound like I'm complaining just to be annoying, but I recently just switched to using SuSE after not using it since 2002 (I've been using Gentoo pretty consistently since then) and I kinda just accept the surprises from Eris as a given with portage, I was just kinda hoping for seamless to be a little more seemless. If I have the wrong idea about this I might as well just go back..

dup operates based on the set of enabled repositories. If I got you right and you had a Leap-15.1 installed, you should not use the openSUSE:/Tumbleweed repo. It's likely that dup switches to newer package versions it finds in TW. It's usually not a good idea to mix packages from TW and Leap. If this is actually the case, maybe this comment helps to check and repair it.

[paigeadelethompson]

Gotcha, yeah that would explain it though I'm not sure how I ended up with tumbleweed packages if I have leap installed, I must have added packages from tumbleweed by mistake thinking it was the same thing I had installed, the names leap and tumbleweed weren't entirely distinct to me until a minute ago :)

I don't mind terribly, though I'll need to be careful not to run into this problem on my server / hypervisor xD

also I just finished recompressing everything, and I'm gonna give this another shot with /var/cache/zypp linked to a dir on /home for now. Anyway i have a few things that may be worth noting about disk space usage:

IIRC df is not the best to use for btrfs:

And I did a defrag / compress pass on both filesystems with btrfs fi defrag -r -czlib Now I've restarted zypper dup

It seems like it should be able to do this now, and when it's finished there should be 2GB free of the 8.9GB thats free as it stands. I guess we'll see in a minute :)

[paigeadelethompson]

Actually I just decided last second not to because it would take way too long to finish and just removed the Tumbleweed repo and as per the fix link that you suggested that was indeed among one of the repositories that shouldn't have been enabled along with "msvec" (Michal Svec?) I think there was something I wanted from that but I can't remember what it was exactly, I think something having to do with certificates because I was trying to get secureboot to work right with a custom kernel that I compiled.

That's interesting though that somebody did the exact same thing that I did. Thanks for the help with that :) I would be interested though sometime in seeing how this can handle that big of an upgrade, just not today though xD
