sysstat VS archinstall

Well... What that's showing is that at some point in time you copied some pages into swap. Since there's no competition for that, they have just stayed there. It doesn't mean that you are seeing memory pressure now, only that at some point since the last reboot your memory usage passed the high water mark which encouraged the kernel to start thinking about swap. If you have sysstat installed you can run through sar to see when that was and even get some idea of whether or not any of those pages written to swap were ever read again, but just having some pages written to swap doesn't mean a whole lot on its own.

You can try sysstat/ iostat. https://github.com/sysstat/sysstat Have a cron or systemd process take periodic snapshots and log them or email them. The swordfish on paper looks fast enough, but it’s on the slow side for a NVMe. For reference I’m running a NUC8 i5 with 16GB of RAM, 1 TB Adata XPG SX8200 Pro and it’s been rock solid. Ubuntu 20.04LTS.

In any case, have you studied https://wiki.archlinux.org/title/Archinstall and https://github.com/archlinux/archinstall. While archinstall is new and has the expected bugs, I've not had your issues before. You might try an earlier ISO, like Oct 2023, though it's not clear if you're using an ISO or the archinstall installed package.

I'm using my laptop as dual boot between Manjaro and Windows 10, I tried for months to install ArchLinux using archinstall tool but the operation always fails with random errors, because I want to install it on a single ext4 partition like how Manjaro is installed. Is there any trusted GUI installer that uses calamares and can install pure ArchLinux ?

The related issue https://github.com/archlinux/archinstall/issues/1111 implies it's fixed, but either way, you can just securely delete your password after the install.

Mount that partition as /efi. Change this in your /etc/fstab as well. This is a good time to remove all the weird carriage returns that archinstall puts in your fstab file (https://github.com/archlinux/archinstall/issues/1399).

Most distros have a nice graphical installer which does make things less of a hassle. But these days Arch also bundles archinstall which is quite easy to use and supports a few display environments for automatic setup right out the gate which is nice.

Or just use archinstall which is official part of the iso file.

You can post an issue at: https://github.com/archlinux/archinstall to get the attention of the developer. He's represented here but I forget his user id.

If you're still suffering with this problem: Maybe try to find the file/module on your system. If it's present, you might want to try to run this pacman -Sy python archinstall (found it here: https://github.com/archlinux/archinstall/issues/1810) to reinstall python and the archinstall script. I hope that this helps you.

Still feels that it is in rapid development phase, rather than just maintenance, last month I encountered this bug
