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.

[arch-general] godep has been deprecated in favor of dep
by Adam Levy 11 Mar '18

11 Mar '18

Hello Today I noticed that as of about 30ish days ago godep ( github.com/tools/godep) has been archived and is no longer supported. The go dev team recommends using dep (github.com/golang/dep) instead. As Arch strives to be as up to date as possible I suggest removing godep from the official repos and potentially moving dep into the official repos from the AUR. The AUR dep package appears to be well maintained. Relevant links: https://github.com/tools/godep https://github.com/golang/dep https://aur.archlinux.org/packages/dep/ Thanks!

[arch-general] Intel microcode - latest version not loading
by Dutch Ingraham 03 Mar '18

03 Mar '18

Hi all: I'm having an issue with Intel microcode loading. Specifically, the microcode does not appear to be loading the latest version: ~ $ dmesg | grep microcode [ 0.000000] microcode: microcode updated early to revision 0x19, date = 2013-06-21 [ 0.931272] microcode: sig=0x106a5, pf=0x2, revision=0x19 [ 0.931319] microcode: Microcode Update Driver: v2.2. My processor is: ~ $ grep -E 'family|model|stepping' -m 4 /proc/cpuinfo cpu family : 6 model : 26 model name : Intel(R) Xeon(R) CPU W3503 @ 2.40GHz stepping : 5 The Intel website indicates the latest version of microcode for this processor is version 20171117 [1]. However, as indicated above, the version loaded at boot is dated 2013-06-21. I have the latest stable version of intel-ucode installed: ~ $ pacman -Q intel-ucode intel-ucode 20180108-1 I have updated GRUB with <grub-mkconfig -o /boot/grub/grub.cfg>, and rebooted. The grub.cfg file shows, as the last line in the menuentry: 'initrd /boot/intel-ucode.img /boot/initramfs-linux.img' I am using a stock kernel: ~ $ uname -a Linux arch2 4.15.5-1-ARCH #1 SMP PREEMPT Thu Feb 22 22:15:20 UTC 2018 x86_64 GNU/Linux Can someone help me determine what is going on here?

[arch-general] emby-server package outdated
by Patrick Dijkgraaf 28 Feb '18

28 Feb '18

Hi all, I hope this is the right place to ask, the bugtracker says to use "the Mailing List", but not which Mailing List, for reporting outdated packages... If this is the wrong place, please point me to the right one! Here's the info: * Package name: emby-server * Current version in the Arch repo: 3.2.60.0-1 * Last updated: 2017-12-23 14:43 UTC * Flagged out-of date: 2018-01-18 (shortly after version 3.2.70.0 was released) We are now more than a month later, and another new version has been released, namely 3.3.0.0. What would be the way to go to get this package updated? -- Cheers, Patrick Dijkgraaf

[arch-general] dhcpcd-7.0.1-1 seems to break SLAAC
by Jukka Salmi 26 Feb '18

26 Feb '18

Hello Since upgrading dhcpcd from 6.11.5-1 to 7.0.1-1 my (VLAN) interface doesn't get an IPv6 address (via SLAAC) anymore. The netctl profile in question: Interface=enp0s25.100 Connection=vlan BindsToInterfaces=enp0s25 VLANID=100 IP=dhcp IP6=stateless With dhcpcd-6.11.5-1 starting this netctl profile results in an IPv4 address being configured via DHCP and an IPv6 address being configured via SLAAC as expected. With dhcpcd-7.0.1-1 starting this netctl profile results in an IPv4 address being configured via DHCP, but no IPv6 address is configured. In both cases, netctl passes dhcpcd the same arguments: dhcpcd -4 -q -t 30 -L enp0s25.100 so that's probably not the source of the problem. If I disable IPv4 DHCP (by setting `IP=no' in the above netctl profile), SLAAC works fine again (but of course then I don't get an IPv4 address via DHCP anymore...). Is anybody seeing the same issue? Is really dhcpcd to blame? TIA & cheers, Jukka -- This email fills a much-needed gap in the archives.

[arch-general] linux kernel 4.15.4-1 un-bootable
by David Rosenstrauch 24 Feb '18

24 Feb '18

Ran into a weird issue today. I upgraded a bunch of packages, including the kernel to v4.15.4-1 (from 4.15.3-1). But for some reason the system was un-bootable. The boot process would get part-way through, then the booting screen would suddenly start showing its text on a green background (rather than black) and it would freeze. It took some jumping through hoops, but I was eventually able to boot to a chroot environment, upgrade to a newer kernel (v4.15.5-1) and suddenly the problem magically went away and my machine boots fine. Anyone have any idea what might have happened here? I'm assuming it was a bad kernel build, but I'd like to know for sure. I didn't see any recent bugs under the "linux" kernel package that matched what I was seeing. Thanks, DR

[arch-general] Please update VLC to v3.0.0
by Xorg 23 Feb '18

23 Feb '18

Hi everybody, I hope it's the good mailing list to request package update (the bug tracker only says 'the Mailing List'), and I'm sorry if I'm wrong. VLC has been flagged out-of-date on 2018-02-07 (2 weeks ago). Can you update it to v3.0.0, please? Thank you in advance! PS: Sorry for task #57595.

[arch-general] After 4.15.4, Arch dhcpd clients on LAN get new IP, but zone update fails (server - bind w/dynamic update)
by David C. Rankin 23 Feb '18

23 Feb '18

All, Not sure if this is kernel or dhcpcd related, but after update to 4.15.4 tonight ArchLinux clients on LAN receive new IP from server (which have not changed in 4-years before), and server DNS zones are not updated, but instead retain the old IP. The error is a general "Has an address record but no DHCID, not mine." (which may be a holdover from an earlier bind failure) Regardless, this has never before caused dhcp4 to issue a new address while retaining the old in the zone files for any Arch client in the 50 or so kernel updates before 4.15.4. (and this was consistent for each Arch box after the 4.15.4 kernel update) Take it for what it is, just be aware if you are admining a remote Arch box that gets its address via dhcp, you may end up with a new address while the old is still reported by nslookup. Just strange... No replay necessary, unless you have an idea of what changed between 4.15.3 and 4.15.4 that may cause this behavior. -- David C. Rankin, J.D.,P.E.

[arch-general] What files are tipically in /usr/local/share?
by Marcelo "Marc" Ranolfi 21 Feb '18

21 Feb '18

Hi, I've just accidentally deleted my '/usr/local/share' folder. This happened while I was creating custom copies of launchers from /usr/share/applications. Now, if I understand it correctly, the '/usr/local' directory should only contain files created by the user. In fact, I checked other subdirectories (bin, etc, games, include, lib, man, sbin, src) and they are all empty, except for a couple files I manually created in 'sbin' and 'lib'. But, as I was almost sure that the 'share' dir specifically was _not_ empty before I started messing with it, I just ran 'pacman -Qkq' and it reported '/usr/local/share/man' missing. This was promptly fixed by reinstalling the 'filesystem' package. But this has me wondering if there was something more important which resides there. Perhaps something generated by an application or script. None of my backups include that directory, so I'm afraid this makes me impossible to check for myself, other than installing/configuring everything from scratch. Can you guys clarify this for me? In case it's relevant, my desktop stack has Cinnamon, LightdDM, networkManager, Samba and other less important packages on top of a standard Arch Linux setup. Thank you, Marc

[arch-general] archlinux install bottleneck
by Jude DaShiell 19 Feb '18

19 Feb '18

After having run arch-chroot /mnt /usr/bin/bash one of the things I do is to run alsactl store. alsactl store returns error 125 /var/lib/alsa/asound.state no such file or directory. Certainly there's no such file since when alsa was run before arch-chroot got run on system boot /mnt/var/lib/alsa directory was empty having just run pacstrap on /mnt. So since this is supposed to work, could it be arch-chroot script fails to collect and pass along enough of the right environment information to its chrooted environment for alsactl store to run? Details are available at: information at: http://www.alsa-project.org/db/?f=43f6670eb3bde26ad6491d2faa631625109f88d0 --
