DKIM fail messages
by David Rosenstrauch 13 Nov '22

13 Nov '22

After posting a message to this list earlier today, I immediately received nearly a dozen DKIM fail messages, all being sent by the "OpenDMARC Filter" at various domains, and all saying that the DKIM fail reason was "signature verification failed". I raised this issue with support at my hosting company, who pointed out that a) my domain's DKIM records are set up correctly, and b) one of the headers on my email that got sent to the list indicated that Arch's mailman actually did successfully verify my domain's DKIM record when it received my email, before forwarding it on. Anyone know why these fail messages might be happening? Is this being caused by a misconfiguration in Arch's mailman installation? Or is this a misconfiguration of the individual OpenDMARC software installations at each of those domains? Thanks, DR

Keeping desktop PC and laptop in sync
by Joel 07 Nov '22

07 Nov '22

Hi, as we have a discussion ongoing about setting up a new PC, I thought I could jump in with my current issue : I have retired my laptop and bought a desktop PC. Gone through the fresh installation process (once every 12 years is OK to declutter a bit), and rsync'ed my home directory (parts of it, mostlyskipped ~/.local and~/.config where I found some 10-20 years old files from programs I used once but never since). Now I still want to use my laptop when I'm on the road, which happens rather seldomly (once every 2 weeks), i.e. have my files, my bookmarks etc available on my laptop. Also not only have to sync my /home/$USER but also /root and some more mountpoints (source code, website stuff, audio, video, pictures), totaling around 1.5TB of data I've been playing around with rsync and adding many many exclude rules to a) limit the amount of files being transferred (eg exclude ~/.cache, browser's cache, thunderbird's imap cache etc) so I can keep an overview if something is getting overwritten that I don't want b) keep certain files (especially XFCE config etc) distinct as eg I have 2 monitors on my PC vs only 1 on the laptop -> different menus, window settings etc Now this is pretty tedious, initial rsync's dry-run showed ~700k files that would be sync'ed, which I brought down to 1k after several iterations and adjustment of exclude settings, and this is so far my first run - currently using my laptop and will sync back when I'm home again... let's see how many files will differ then ! So I'm looking for more easy-to-use alternatives. Most important thing : I want dry-run functionality to prevent unwanted data loss, which means automatic sync tools are not the way to go ! I think synthing is such a candidate, unless I missed the dry-run option somewhere. Have used unison many many years ago, but I think it was also not perfect and had issues handling thousands/millions of files. Heard of some new systemd homesync (?), but didn't have a look at it now, sounds also like it automatically syncs. Any thoughts / recommendations / advices ? Many thanks Joel

Setting up new computer to be identical to old one
by Spencer Collyer 01 Nov '22

01 Nov '22

I am looking to replace my current desktop PC, which is getting on for 8 years old now, with a more up-to-date one. Ideally I want the new one to be set up the same as my current one, which has been running on Arch since I first got it. I keep my Arch up-to-date by running a full update roughly every four weeks. What is the best way to set up the new one to mirror the existing one? I'd like to have all the same packages installed, with basically the same setup, except for obvious points like the new PC having a different IP address and name on my network. My initial idea was something like the following: 1) Install a basic Arch system on the new computer 2) Get the list of installed packages from the old computer (I think there is a way to do this using Pacman?) 3) Somehow get Pacman to install the same list of packages on the new computer. 4) Tidy up any config files that need changing - e.g. for the aforementioned IP address / computer name stuff. 5) Copy over my /home directory 6) Copy over various data directories/partitions I have -e.g. I have a whole bunch of images stored in a separate partition that I'll want to copy over. The stuff in here is all self-contained so should be easy enough to copy over. I found thread https://bbs.archlinux.org/viewtopic.php?id=171726 which had some ideas as well - the above is sort-of based on stuff I found on there along with my own thoughts. Does that look like a reasonable plan? Anything I might be missing? Thanks for your attention. Regards, Spencer

Shadowing the boot disk on Arch system
by Spencer Collyer 30 Oct '22

30 Oct '22

Hi, This is sort-of a follow-on to my earlier message regarding how to best set up a new desktop to match the existing one I have running Arch. I'm intending that my new computer will have an M2 drive as the boot disk. As well as the OS it will also hold my /home partition. Because of a bad experience I had with a Windows laptop with an SSD drive installed, where the SSD got completely wiped back to its factory setting, my intention is to have a hard disk that acts as a 'shadow' of the boot disk. The idea is it will also be a bootable drive with exactly the same setup as the M2 drive. That way if the M2 drive dies, I can still boot using this backup drive and the system will look the same. My intention is to have a cron job that periodically (at least daily) synchronises the backup drive so it looks exactly the same as the main drive. Does that sound like a feasible plan? If it is, my question is what is the best way to initially set up the shadow drive? Should I do a full install on it, so almost treating it like I'm setting up a new computer, but making sure I have all the same packages and setup as the main drive. Or should i just use 'dd' to copy the whole main drive over to the backup drive? I'll make sure the two drives are the same size (or rather that the backup is at least as large as the main drive). Or is there another, better, way I haven't thought of or found while trawling the web? Thanks for your attention, Regards, Spencer

Proposal: Do not remove a package from the AUR until it is available in a stable repository
by Óscar García Amor 29 Oct '22

29 Oct '22

Hi all! Recently with the GNOME 43 update I have seen that certain packages are being removed from the AUR to go into the official testing repositories. The problem, in my opinion, is that packages are being removed from the AUR before they go into an official stable repository, which makes the packages "disappear" for a while. Not everyone has the testing repository enabled. In fact using AUR packages is not a condition for having testing, so what a user sees is that suddenly the package he/she was using disappears and he/she can't install it neither with his AUR helper nor with pacman. IMHO, I think it would be better to leave the packages in the AUR until they reach the stable repositories to avoid possible confusion. Greetings. -- Óscar García Amor | ogarcia at moire.org | http://ogarcia.me

Pacman returns error 404
by Zero 27 Oct '22

27 Oct '22

Hi all, Trying to install nodejs with pacman I do experience errors: pacman --sync nodejs Packages (1) nodejs-19.0.0-1 ... :: Proceed with installation? [Y/n] Y :: Retrieving packages... nodejs-19.0.0-1-x86_64.pkg.tar.zst failed to downloaderror: failed retrieving file 'nodejs-19.0.0-1-x86_64.pkg.tar.zst' from geo.mirror.pkgbuild.com : The requested URL returned error: 404 When accessing https://geo.mirror.pkgbuild.com/archlinux with a browser I can download the files nodejs-19.0.0-2-x86_64.pkg.tar.zst and nodejs-19.0.0-2-x86_64.pkg.tar.zst.sig. But when accessing https://mirror.rackspace.com/archlinux with a browser it gives a http error 503 or after a long wait the packages show up. Is there a problem with the pacman mirrors ? ~Zero

gnome 43 / testing - gnome-shell core dumps
by Genes Lists 27 Oct '22

27 Oct '22

Sharing in case helps others avoid having trouble. Update worked fine - once update completed fresh reboot - gdm starts fine - can login - but after that get a blank desktop - nothing at all works. Will go over logs more carefully but looks like gnome-shell is crashing: Process 1181 (gnome-shell) of user xxxx dumped core. The logs are tricky, as gnome spits a slew of error messages at the best of times (this is not new to 43, for me anyway). All 3 machines are intel i915 based; 2 NUCs and an older laptop. I've downgraded to 42 and all works well again. FYI :) gene

If "cp -a" returned exit status 0, the copy is most likely ok, running diff isn't necessarily needed. If tar --xattrs... returns exit status 0, you can't trust it. After doing a backup by tar always (try to) open the archive. However, making a backup using tar first and then restoring from the archive doesn't make sense at all.
