[09:39] <jarnos> What to do when upgrading from 18.04 to 20.04 seems to fail. At least the dialog showing progress of upgrade is corrupted.
[09:41] <jarnos> Actually, before that I restarted upgrade that failed after this: It complained about running xscreensaver. I exited xscreensaver and disabled a systemd scrvice I had for suspending.
[09:42] <pmjdebruijn> what's the exact error?
[09:42] <jarnos> The restarted upgrade continued as partial upgrade and seemed to work for a while.
[09:42] <jarnos> I don't know. The dialog is corrupted and I don't know what it is doing.
[09:42] <pmjdebruijn> what does "corrupted" mean?
[09:43] <pmjdebruijn> but if so, run the upgrade on a terminal as opposed the GUI
[09:44] <pmjdebruijn> though, personally I prefer reinstalls as opposed to upgrades for desktop systems
[09:44] <jarnos> It does not draw its content. If I e.g. use alt-tab to switch the app on foreground and switch back, it has the content of the other app.
[09:45] <pmjdebruijn> like I said, do the upgade on the console
[09:52] <jarnos> Well, I think package management is corrupted. dpkg is in interuptable sleep. I guess it is holding back the dialog.
[09:53] <pmjdebruijn> that does not happen easily
[09:54] <pmjdebruijn> jarnos: reinstalling may very well be faster, and you end up with a clean system, as opposed trying to fix your current situation
[17:33] <hereiamsorryandh> Hello, I'm going to buy a computer and run Xubuntu on it. The CPU is Intel Pentium E5400, an old one as you see. The question is… how can I find out if Xubuntu (and Steam especially) is supported on this CPU? I googled and found out it's 64-bit, that's fine. Then I found out it (highely-likely) supports SSE. So that's also fine. The thing I
[17:33] <hereiamsorryandh> struggle is I can't or don't know how to find out if it supports CMPXCHG16B instruction (also called cx16). It is required for Steam (and maybe Chrome I guess and such things)
[17:34] <hereiamsorryandh> SSE3*
[17:37] <diogenes_> hereiamsorryandh, the best way is to boot Xubuntu live and see what works.
[17:38] <hereiamsorryandh> Hmm I hope the owner will let me do that. But I can't install Steam on Xubuntu live just to launch it to see if it works at all.
[17:38] <diogenes_> hereiamsorryandh, yes you can.
[17:40] <hereiamsorryandh> How? Without changing the files on the owner's HDD? Can I? Will 'cat /proc/cpuinfo/' work on any machine?
[17:41] <hereiamsorryandh> Without a slash in the end
[17:41] <kryten> hereiamsorryandh: https://unix.stackexchange.com/questions/43539/what-do-the-flags-in-proc-cpuinfo-mean - definitely could just do this on a Live system though.
[17:41] <kryten> ..Oh, yeah! XD
[17:43] <diogenes_> hereiamsorryandh, it will install steam on live system and you will also check if wifi works and GPU and if it boots at all.
[17:43] <hereiamsorryandh> Peeeeerfect! I always thought that /proc/cpuinfo is just a file on an ALREADY INSTALLED os :D Then I was wrong
[17:43] <diogenes_> and also check the temperature.
[17:45] <hereiamsorryandh> I wonder, if I install something on live system, where will the files be stored? It's interesting…
[17:45] <diogenes_> on temporary space within USB drive.
[17:46] <diogenes_> it won't affect HDD.
[17:46] <hereiamsorryandh> Wow, just wow. It's gonna be slow tho. But it's worth it.
[17:46] <kryten> Actually, unless the medium is set up with persistency, just in RAM.
[17:49] <diogenes_> if you boot the machine and after a minute or two the temperature goes high and fans make noise, i won't buy it.
[17:52] <hereiamsorryandh> Thanks for the answers and the pieces of advice, I appreciate
