[arch-general] Package conflicts
by Jonathan Arnold 25 Mar '14

25 Mar '14

I'm having a problem with the liteide vs gocode-git packages. liteide, which is an official Pacman package, has recently started to include the /usr/bin/gocode binary, which I have been using via the AUR package gocode-git (there is also another AUR package called gocode-bin but no pacman package). So now when I try to update I get an error: error: failed to commit transaction (conflicting files) liteide: /usr/bin/gocode exists in filesystem This didn't seem to be right, as I'm trying to install liteide, not gocode here. So I reported the problem: https://bugs.archlinux.org/task/39607 and it immediately got closed with the statement that AUR packages aren't supported so contact the maintainer of the AUR package. Well, as far as I can tell, there isn't much the maintainer of the AUR package can do if some other package is going to just put any old binary wherever it wants without saying anything about it. Shouldn't the liteide package at least say it provides 'gocode'? Or conflicts or something besides just letting pacman complain about a file that exists in the filesystem? Carrying this a bit further, how would it or should it work if I did want to keep using gocode-git, but also use liteide? -- Jonathan Arnold Webstream: http://hieronymus.soup.io If you want to go fast, go alone.

As root, enter the command 'su a' and not prompted for a password. 'less /etc/shadow' shows the password for the user. Interestingly, 'su a' results in the cursor 'pwd' to be the root home directory and not '/home/a'. > > Do you have the correct graphics drivers installed (xf86-video-*)?

[arch-general] [contribution] Pages from Arch Wiki optimized for offline browsing
by Jakub Lahwaacz Klinkovský 23 Mar '14

23 Mar '14

Hello all, I would like to present my most recent work: arch-wiki-docs-clean [1]. The package provides pages from the Arch Wiki, optimized for offline browsing, meaning they contain only the content, all MediaWiki navigation components are removed. While I was at it, I have also fixed another bugs found in the existing arch-wiki-docs [2] package: internal links with fragments (i.e. links to sections) are working. While there is still some work to be done [3], I think it is already much better than community/arch-wiki-docs. Downloading all pages from the wiki takes some time, so I have a package pre-built for you: [4]. Alternatively, you the HTML pages are dumped into 'dump_html' branch on Github (the PKGBUILD will use them by default). I will appreciate any feedback as well as suggestions for future development, I hope somebody will find it useful. Regards, [1]: https://aur.archlinux.org/packages/arch-wiki-docs-clean/ [2]: https://www.archlinux.org/packages/community/any/arch-wiki-docs/ [3]: https://github.com/lahwaacz/arch-wiki-docs/issues [4]: http://lahwaacz.sh.cvut.cz/ -- jlk

[arch-general] user management error
by message 23 Mar '14

23 Mar '14

Readers, A previously existing /home directory was mounted into the file system during the installation process; this directory contained files in a directory 'a'. A user was created from the root user account: useradd -M -p [password] -s /bin/bash [username'a'] After reboot, the system is restarted as root because the user 'a' is stated to not exist. The command 'cat /etc/passwd' reveals a password 'x', but this is not the password that was entered. How to solve this error?

[arch-general] BTRFS scrub from systemd unit
by Sean Greenslade 20 Mar '14

20 Mar '14

Hi, folks. I've been noodling over this rather odd issue I've been having, and I thought I'd get a second opinion on things. I've got a server with four hard disks, set up in two (separate) BTRFS RAID1 mounts. I just recovered from a bout of SATA signalling issues (which BTRFS did a marvellous job of saving my data from), and I'd like to periodically fire off scrubs to ensure my data's OK. If I manually run a scrub: ---------------------------------------------------- $ sudo btrfs scrub start /media/data/ scrub started on /media/data/, fsid 490b8b7c-59c4-45dc-ac63-6a90f0966776 (pid=14434) ---------------------------------------------------- Then things work as they should: ---------------------------------------------------- $ sudo btrfs scrub status /media/data/ scrub status for 490b8b7c-59c4-45dc-ac63-6a90f0966776 scrub started at Wed Mar 19 20:27:14 2014, running for 40 seconds total bytes scrubbed: 12.70GiB with 0 errors $ sudo btrfs scrub cancel /media/data/ scrub cancelled $ sudo btrfs scrub status /media/data/ scrub status for 490b8b7c-59c4-45dc-ac63-6a90f0966776 scrub started at Wed Mar 19 20:27:14 2014 and was aborted after 89 seconds total bytes scrubbed: 28.17GiB with 0 errors ---------------------------------------------------- So far, so good. So I made a systemd unit to trigger the scrub: ---------------------------------------------------- $ cat /etc/systemd/system/diskscrub.service [Unit] Description=Disk scrub runner [Service] Type=oneshot ExecStart=/usr/bin/btrfs scrub start /media/data ---------------------------------------------------- Now, this unit starts fine, and exits immediately as it should, being a oneshot service and given that the btrfs scrub command backgrounds itself (or something? I'm not exactly sure what it does, but it returns immediately). However, the scrub status does not work and the scrub cannot be canceled: ---------------------------------------------------- $ sudo systemctl start diskscrub $ sudo systemctl status diskscrub diskscrub.service - Disk scrub runner Loaded: loaded (/etc/systemd/system/diskscrub.service; static) Active: inactive (dead) Mar 19 20:33:38 rat systemd[1]: Starting Disk scrub runner... Mar 19 20:33:38 rat systemd[1]: Started Disk scrub runner. Mar 19 20:33:38 rat btrfs[15221]: scrub started on /media/data, fsid 490b8b7c-59c4-45dc-ac63-6a90f0966776 (pid=15222) $ sudo btrfs scrub status /media/data/ scrub status for 490b8b7c-59c4-45dc-ac63-6a90f0966776 no stats available total bytes scrubbed: 0.00 with 0 errors $ sudo btrfs scrub cancel /media/data/ ERROR: scrub cancel failed on /media/data/: not running ---------------------------------------------------- New scrubs cannot be started until the stale/invalid scrub states are deleted (rm -f /var/lib/btrfs/*). So I'm stumped, here. Anyone have any clue as to what's happening? Thanks, --Sean
