13 Jun '18

Hello, The class Python for Beginners - Part 1 will be held on Wednesday, October 04, 2017 at 16:00 UTC in the channel #archlinux-classroom on the freenode network. The class is expected to run for about 2 hours. This class will introduce you to programming with Python and how to use IPython with an editor/IDE. Commonly used built-in functions and libraries will be explained. Other topics will explored based on participant interests. The class will be screen-shared live (via YouTube), and later archived with subtitles. Questions and some discussion on IRC is expected, however the main part will be video and audio. In preparation for the class, install the Jupyter notebook. ``pacman -S jupyter`` or, in a Python 3 virtualenv, ``pip3 install jupyter``. Also check out the python-beginners git repository on Arch Classroom's GitHub[1] where you will find IPython notebooks and links to useful resources on learning Python: https://github.com/archclassroom/python-beginners pulec is an Arch Linux user since 2012, gamer and gardener.

Hello, Why is there no NetworkManager in ArchISO? Isn't it widely accepted as the go to method of connecting to internet in Linux? Is there any reason for it not to be default? Thanks J

Re: [arch-general] [Solved] Switch from AMD GPU to nvidia GPU
by Foxtrot Mike 31 Dec '17

Hi, Thanks for the reply. So I re-installed the AMD graphics card. Updated the system with 'pacman -Syu'. Created a bootable arch USB. Shut the PC off and installed nvidia card. Booted up the system. Everything worked fine this time. Don't know what the issue was but perhaps updating the system resolved it.

[arch-general] Setting make options for aur-packages
by Jeanette C. 28 Dec '17

28 Dec '17

Hey hey, is there a simple, systematic option to set make options for building AUR packages, that are compiled on the local system? I know that I can edit the PKGBUILD file for each package, but I'd prefer something global. My goal is to build using multiple jobs (-j option for make). I searched options and environment variables for aurget and makepkg, without result. TIA and best wishes, Jeanette -------- * website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c Just hang around and you'll see, There's nowhere I'd rather be <3 (Britney Spears)

[arch-general] [archlinux] shepherd in Arch
by Javier 26 Dec '17

26 Dec '17

Hi, Looking into [1] and [2], I noticed it's possible to get openRC working from AUR in Arch, but more importantly, seems like it's also possible to get shepherd working on Arch from AUR [1][3]. However, as opposed to openRC, shepherd seems less documented. Both shepherd and openRC appear as integrated inits for Arch... Any documentation on migration to shepherd from AUR? Please notice my intention is not to start a discussion about inits. I know systemd is the "de facto" init for Arch. I just would like to try shepherd on Arch. If possible using besides eudev, also elogind, which seem also available from AUR. And all this from AUR... Thanks, -- Javier [1] https://wiki.archlinux.org/index.php/Init [2] https://wiki.archlinux.org/index.php/OpenRC [3] https://aur.archlinux.org/packages/shepherd

Hi everyone, I'm struggeling with my laptop : I can't manage to boot into any Linux distribution. My laptop is an HP Elitebook x360 G2 ; BIOS P80 01.09 Rev.A (up to date). By turning off every "protection" I'm able to select the USB stick in the boot menu ; but I can't pass this step. I immediately go back to the boot menu. Does anyone knows how to install Arch on one of thoose #@$&=%* machine ? Many thanks, Tom

[arch-general] netctl multiple dns servers
by David Rosenstrauch 24 Dec '17

24 Dec '17

I'm using netctl to initialize my server's network stack, using a tweak of the "ethernet-static" example profile. I'm specifying a list of DNS servers, but only one of them is winding up in the resolv.conf file. I'm wondering why/how to fix. In my netctl profile: DNS=('127.0.0.1' '208.67.222.222' '208.67.220.220') The resulting resolv.conf: # Generated by resolvconf nameserver 127.0.0.1 Any idea what the issue is? Does netctl not correctly handle an array of dns server names? Thanks, DR

[arch-general] How to build package in "clean chroot" using the "-U" parameter?
by Manuel Reimer 22 Dec '17

22 Dec '17

Hello, I want to autobuild a set of packages. For this process, it is not acceptable to use "sudo" as I don't want to enter some passwords and my autobuild program also has to do some other stuff with root privileges. The help page of "makechrootpkg" suggests, that there is an option for me: -U Run makepkg as a specified user But I tried this several times. So far without success. I've copied the PKGBUILD to the /tmp directory, just to be sure it is really readable by my build user. Then my command was: # makechrootpkg -c -U build -r /var/cache/PATH_TO_MY_CHROOT This now seems to download the source files and also is validating them against the stored MD5 sums. But after that I get the error ==> ERROR: Running makepkg as root is not allowed as it can cause permanent, catastrophic damage to your system. Seems like makepkg is called once in context of my supplied "build user" and then a second time without using the build user. Where is my mistabe? Or is this a bug in makechrootpkg? Thanks in advance Manuel

[arch-general] No ipv6 address - but only on one machine
by David Rosenstrauch 22 Dec '17

22 Dec '17

Having a weird situation going on with IPv6. Every machine on my network can successfully get an ipv6 address except for one. (My main server.) What's even weirder is that ipv6 was working on that machine up until probably about a week ago. Not sure what the problem is, and hoping someone here might be able to offer a pointer. Here's the scenario: 1) Wifi router reports an IPv6 address on both the WAN and the LAN sides. (In the 2607: range.) 2) Mac desktop behind the router successfully gets assigned an ipv6 address. 3) Linux laptop (running Arch) successfully gets assigned an ipv6 address (using NetworkManager). 4) Linux server (also running Arch) does not get assigned an ipv6 address. The server is using netctl for networking, and its profile includes: ## For IPv6 autoconfiguration IP6=stateless Yet for some reason, this machine doesn't get assigned an external ipv6. Rather it only gets assigned one in the link-local range. (I.e., in the fe80: range.) I have to admit this is pretty puzzling. I can't for the life of me figure out why the server can't get an address. Particular since it was able to do so successfully probably about a week or so ago. Anyone have an idea what could have happened here? Has there been some package update recently that might explain this? Or any pointers on how I might go about debugging this? Thanks, DR
