    I went over the Essential Programs for LFS – 2.2.2 Host System Software. Many of them should have been installed with the development tools that I installed after setting up Ubuntu. I checked the version of all of them and wrote them in the manual. My notes include: Checking version of coreutils – use any…

  • Thinking about partitions

    Trying to make some decision about partitions to carry out LFS 2.4 Creating a New Partition. After reading the manual, material online, the hints, the explanations of the hints, none of which I understood, I started to come to the conclusion that: –I’ll have only one /boot/EFI partition on the drive. On it, Ubuntu GRUB…

    I used balena Etcher to flash the GParted Live download to the Celeron USB. gparted-live-1.6.0-10-amd64.iso was successfully flashed to General UDisk So there!

  • Looking at the flash drive

    I got a separate flash drive for GParted, a Celeron. I installed GParted on the Numbat PC to look at the flash drive and kind of see how GParted worked. (Although I think I might also have installed it on the Fossa PC at some point.) sudo apt updatesudo apt install gparted It looks like…

    gparted-live-1.6.0-10-amd64.iso – 550 MB Downloaded checksums.txt and checksums.txt.gpg Verified ISO Verified iso using “How to verify a downloaded file” as I post this I don’t know where that particular piece of paper is or what I did. I hate checksums. I got more used to them later in LFS chapter 3.2. Testing executables gpg, md5sum,…

    balenaEtcher-linux-64-1.19.25.zip – 14 MB To remind myself what I did with it: Appimage in Home Run it by opening its folder, click on balena-etcher

    Practicing the uname command: uname Linuxuname -m x86_64 x86_64 meaning Intel or AMD 64-bit. I guess the Numbat mininPC is Intel. Trying it out on my Mac mini M1: uname -m ARM64

  • The UNetbootin rabbit hole

    The GParted website was really insistent about using UNetbootin to flash the GParted Live USB (even though I felt that balena Etcher must be equivalent). UNetbootin won’t install for Ubuntu 24.04. I tried this stuff: sudo add-apt-repository ppa:gezkovacs/ppasudo apt-get updatesudo apt-get install unetbootin I learn about the error message here: https://itsfoss.com/repository-does-not-have-release-file-error-ubuntu/ I could use the…

  • Hold snaps forever

    I’m pretty sure the weird stalling on Firefox (that is, when I’m actually trying to use the Numbat computer) is from snaps downloading themselves in the background without any notification. I did this: snap refresh –hold-forever “Auto-refresh of all snaps held indefinitely” TG For whatever reason, I don’t think snaps auto-download on the Fossa miniPC,…

  • SecureBoot, snaps, and planning

    SecureBoot Secure boot is already disabled: sudo mokutil –sb-state “SecureBoot disabled” Was it never on or did I unintentionally disable it when clicking around in the BIOS? On 11/29, I used the mokutil command on the Focal Fossa miniPC. That too has “SecureBoot disabled.” The Fossa’s platform is “in setup mode,” which is supposed to…
