Hello Steve Can you point out how you configured your system? (How many disks, how they are partitioned) Do you install grub on an UEFI system? What was the grub-install command you used? - Patrick Steve Downes <steve(a)kingswayelec.co.uk> schrieb am So., 2.

[arch-general] /etc/libvirt/qemu/network/default.xml.pacnew permission change?
by David C. Rankin 08 Apr '17

08 Apr '17

All, The original /etc/libvirt/qemu/network/default.xml has 0600 permissions, the new /etc/libvirt/qemu/network/default.xml.pacnew installs with 0644, is there any significance to the permission change or does the .pacnew just need to be put in place with 0600? (or does it matter?) -- David C. Rankin, J.D.,P.E.

[arch-general] Link against system libs
by Wolfgang Mader 07 Apr '17

07 Apr '17

Hi all, I have a general question about linking in C++ with which you can probably clarify for me. Arch ships with a lot of libraries of which .a and .so are stored in /usr/lib and beyond. These libraries are compiled by some compiler, the compiler by which the entire arch linux distribution packages are compiled with. By the way, which one is this and where can I find that information. If this compiler is a c++ one, it does its specific name mangling. Thus, linking against these libs should only be possible for binaries compiled with the same c++ compiler. However, arch ships gcc6, gcc5, and clang. Does it also ship libraries for all these compilers or how is it possible for binaries complied by these different compilers to link successfully? Best, Wolfgang

[arch-general] Mount point of MTP devices?
by Rijul Gulati 05 Apr '17

05 Apr '17

Hello, I have recently installed Arch on my desktop machine (KDE). I want to access android device (MTP) from terminal. The device is accessible from file manager (Dolphin). This means it has to be mounted somewhere (right?). It's not mounted in '/run/user/1000/gvfs' directory I have following packages installed: gvfs-mtp 1.30.3-1 libmtp 1.1.12-1 mtpfs 1.1-2 Where are mtp devices mounted?

[arch-general] Suppressing specific pacman warnings
by João Miguel 05 Apr '17

05 Apr '17

Hello, I have some unofficial repos added in pacman.conf, and at times use ABS and the AUR, so I often get messages like this: # LANG=C pacman -Syu ... :: Starting full system upgrade... warning: udevil: local (0.4.4-2) is newer than community (0.4.4-1) ...(10 messages from unofficial repos)... First of all, why is this a warning? What is the problem of me having a newer version of a package than the repository? --quiet does not help. I could do # pacman -Syu 2>/dev/null but this supresses *all* warnings. Also if I need to hold ignore a few packages, I get this (which actually makes more sense as a warning): warning: haskell-src-exts: ignoring package upgrade (1.17.1-8 => 1.18.2-4) which I know already, since I'm the one who put it IgnorePkg. I looked in the manpage for pacman.conf and also found nothing to quiet specific warnings like this. Could they at least be less verbose? Say, in one line: warning: ignoring (42) package updates (for nvidia, nvidia-dkms, haskell-src-exts, ...) I found this old bug report (https://bugs.archlinux.org/task/31594) regarding this, but there's no decision about it. I'd like there to be an option to quiet these, possibly in pacman.conf: QuietWarning = NewerThanRepo | IgnoredUpdate | ... What do you think? Thanks in advance for any suggestions. João Miguel

You could use basic shell redirection; pacman -Syu 2>&1 | egrep -v "is newer than" The example uses egrep because that is easy with multiple patterns (seperated with pipe symbols). For real ease, test a few cases, then make a function of it. Mvg, Guus Snijders

Can someone point me at what I've missed please:- I'm doing a new installation of archlinux & got as far as installing grub apparently without problem. Installing grub gives:- Failed to get canonical path of `airootfs' This means nothing to me & I can't find anything. Could use some guidance before I start again, or even better instead of starting again. Steve

[arch-general] Removing gitolite package doesn't remove gitolite user
by Ricardo Band 02 Apr '17

02 Apr '17

Ahoi, I was removing gitolite because I fucked my setup up. When I reinstalled it to start from scratch, I ran into a problem. The /var/lib/gitolite folder wasn't created when I reinstalled the package. I found out that the gitolite user also still existed. I removed it and reinstalled gitolite. Now the directory was created like it should. I think this is a bug. When gitolite is uninstalled it should also remove the gitolite user. If the user is for some reason still needed after uninstall, another solution would be to correctly recreate the /var/lib/gitolite directory when installing the package and the gitolite user is detected. -- Greetings Ricardo Band https:// www.ricardo.band mailto:// email(a)ricardo.band

[arch-general] install Arch on Btrfs - dual boot w10/arch - can't find vmlinuz on boot menu
by arnaud gaboury 01 Apr '17

01 Apr '17

I followed the arch install wiki to install arch alongside w10 and dual boot. (w10 was already installed). Here is a summarize of the output of fdisk: ---------------------------------------------- # fdisk -l Disk /dev/nvme0n1 /dev/nvme0n1p1........ 260M EFI System /dev/nvme0n1p3......... 186G Microsoft basic data /dev/nvme0n1p6......... 264.7G Linux filesystem -------------------------------------------------------- I formatted the Linux partition with Btrfs. In short: # mkdir /mnt/btrfs # cd /mnt/btrfs # btrfs subvolume create /mnt/home I created this way 5 subvol: ROOT, home, etc, .snapshots, development --------------------------------------------------------------------- Then generated fstab. Here I have a first doubt about how it has been done. The first line is : ------------------------------------------ #/dev/nvme0n1p6 LABEL=daffodil-root UUID=xxxyyyyy / btrfs rw,noatime,compress=lzo,ssd,subvolid=261,subvol=/ROOT,subvol=ROOT 0 0 ---------------------------------------------- ---> Question 1: why twice subvol ? Is it normal or shall I delete one? Then, still on install, I followed systemd-boot wiki. Once arch installed and chrooted, I did the following (*here I have doubts about my method*). I 1- mounted the EFI partition (/dev/nvme0n1p1) on /boot 2- bootctl --path=/boot install 3- copied the linux stuff (initramfs, vmlinuz...) on /boot. I finished with a /boot folder populated as described in systemd-boot articles. ---> Question 2 Then I wrote an enter in fstab for the vfat boot partition. I AM NOT SURE AT ALL I have to do this. Once installed finished, I rebooted. The systemd-boot menu appeared as expected, but didn't work as it was unable to find vmlinuz neither w10. ~~~~ Back to the install script, I try to fix things now. I first mounted the Linux partition in /mnt. I can see all the created btrfs subvol when running btrfs subvolume list ---------------------------- # btrfs subvolume list -p /mnt ID 261 gen 179 parent 5 top level 5 path ROOT ..... ID 267 gen 35 parent 261 top level 261 path ROOT/var/lib/machines --------------------------------------- A few questions: ------> Question 3 : why this line about systemd machines? Is it expected? ------> Question 4 : according to arch btrfs wiki, "Changing subvolume layouts is made simpler by not using the toplevel subvolume (ID=5) as /".It is not my case. How can I change this to avoid using the toplevel as / ? Thank you for your help and hints on: - why dual boot can't find OS - is my btrfs install clean

[arch-general] [mpd+ncmpcpp] mpd hangs when manually moving forward on track, or to nex track
by Javier Vasquez 28 Mar '17

28 Mar '17

Hi all, If someone is familiar with mpd (user, non root) + ncmpcpp on Arch, perhaps can help me out... Whenever I move forward/backward on the same playing track (f/b), mpd just hangs, usually so hard, that mpd needs to be restarted to do anything. A workaround is to pause the track, and then move forward/backward, and then play again, most of the time that works... When playing a track, and then moving to next/prior track (>/<), then mpd hangs. To get it back alive, it's enough to stop mpd (s), and start any track (enter). The pause work around for moving forward/backward on the same track doesn't work, mpd keeps hanging, but stopping mpd (s), and starting any track (enter) works. Stopping mpd (s), to move to the next track as a work around doesn't work, given there's no current track playing, therefore mpd can find the next... So it's sort of weird that moving around where to play mpd, kinds of makes it hang... BTW, I have 2 mpd outputs, the pulse output but also a visual fifo, however by keeping only the pulse audio doesn't help, so It's not related to the visual fifo... Any hint would be appreciated... Thanks a lot, -- Javier
