[00:37] <Manski> Hi all! I'm trying to install a Lubuntu 20.04.2 on my Lubuntu 18.04 PC from a USB flash drive. While I'm trying to boot my PC from this USB drive, I end up getting the following error: "this kernel requires an x86-64 cpu but only detected an i686 cpu
[00:37] <Manski> "
[00:37] <Manski> What could be a problem here
[00:37] <Manski> ?
[01:01] <guiverc> Manski, Ubuntu completed dropped i386 during the 19.04/disco cycle; so existing i386 installs got updates; but new installs were not possible.  i686 implies you're on a i686 cpu & can't run amd64 code that is all that is supported from 19.10 upwards; ie. your cpu is 32-bit only.  (i386-i686 are 32-bit, amd64 is intel/amd 64-bit; named amd64 as AMD created it first)
[01:01] <guiverc> s/Ubuntu completed/Ubuntu completely ^
[01:05] <Manski> guiverc: Thanks again for your reply! My Lubuntu 18.04 is broken at the moment: it won't install system updates. Should I reinstall version 18.04 as it seems that I cannot install a higher version?
[01:07] <guiverc> I would not install 18.10 or 19.04 as they're completely EOL (i386 images existd for them); so 18.04 makes more sense (you're off-topic here as Lubuntu 18.04 support ended on 30-April-2021), so for Lubuntu - 18.04 makes the most sense (`ubuntu-support-status` will show supported packages as regards security upgrades).  Your other option is Debian (I QA-tested Debian 10 or even 11 (officially out Saturday 14-Aug-2021) in boxes I used for 
[01:07] <guiverc> QA-testing Lubuntu 18.04/18.10/19.04 in i386)
[01:09] <guiverc> As Lubuntu 18.04 is now off-topic here (you can still use #ubuntu whilst 18.04 is supported), Debian is offered as an alternative
[01:09] <Manski> Is Debian as lightweight as Lubuntu?
[01:11] <guiverc> Manski, on ONE box I get far greater performance from Lubuntu than Debian 10/buster... I didn't try QA-testing Debian 11 on that box (given how badly 10/buster performed)  That was my least-powerful box; but on most they were pretty close.
[01:13] <guiverc> s/get/got ^   (buster testing was ~2 years ago...)
[01:16] <Manski> This is what I found with my Google search: " I have installed Debian with LXDE. It seems to me in my opinion more customizable, faster (responsive and less memory usage), and more lightweight than Lubuntu. Also, it makes much less disk usage noise
[01:16] <Manski> "
[01:19] <guiverc> I use both Debian & Ubuntu (I treat Lubuntu as Ubuntu)... and I rarely notice differences; I mentioned what I did as I clearly remember it; I didn't expect such a noticeable difference HOWEVER I'm very aware differences vary on CPU & hardware involved..  On pentium M, D & 4 the difference was minimal; but on 'celeron 2ghz' difference was SIGNIFICANT & in Lubuntu's favor.  On c2d, c2q & amd64 capable cpus difference was too small to be 
[01:19] <guiverc> noticeable, at least to me.
[01:22] <guiverc> Debian doesn't provide snap by default (it's available if you want it), that does help size & boot time slightly... Of note: I likely ignore that difference as it's configurable by me (Lubuntu installs with no snaps though); some testers would count that as a difference as it is a valid out-of-the-box comparison point  (Lubuntu being an official flavor must have snaps installable)
[01:24] <guiverc> we're off-topic here, if you have more questions of me, please ask in #lubuntu-offtopic (18.04 isn't supported here)
[07:17] <dragon2> what is SSL?
[07:17] <dragon2> I just noticed lubuntu uses OpenSSL
[07:18] <dragon2> Has it anything too do with secure boot? 
[07:24] <guiverc> openssl is an open source implementation of SSL & TLS protocols (ie. network related), where as secure boot relates to booting a PC
 Hello, i want to suggest something about lubuntu. Imo lubuntu should have better theme as default, at least to make better look to file browser and window title bar.
[07:35] <guiverc> there is a sddm theme task already (https://phab.lubuntu.me/T182)  ; it may not be readable; power outage occurred earlier that may not be fixed :(
[07:37]  * guiverc was trying to find a prior suggestion I recall for theme refresh, but can't currently find links sorry as I can't access phab
[07:59] <dragon2> I like the colibri in lubuntu
[08:01] <dragon2> the desktop environment image
[08:02] <dragon2> earlier editions of lubuntu had more details 
[08:03] <dragon2> not sure what can be improved in the title bars or menu 
[08:22] <frog_blu> Ciao a tutti. Ho appena installato lubuntu su una vecchia macchina (un packard 8 bell) con scheda video integrata, ma il SO sembra andare molto male. Ho assegnato alla scheda video la risorsa massima disponibile dal BIOS (512), ma non c'è verso di velocizzarlo. Consigli? Come ottimizzo da SO la scheda video (una radeon)?
[08:22] <frog_blu> Grazie a chi vorrà rispondermi.

[08:25] <dragon2>  A Packard Bell ?   I don`t know if they will be able to stream videos. If you can install enough RAM it should go on the harddisk. How old is it?
[08:26] <dragon2> He quit, and in Italian 
[08:28] <dragon2> I see there are newer PBs, I didn`t know they stopped making them over 15 years ago
[09:44] <dragon2_> Is lubuntu considered safe on the web? I have no particular virus protection on this computer. I have norton on my windows unit
