Create a static github page with Hugo Install Hugo on Ubuntu 22.04 apt install hugo Create github repositories Login to github.com; Create two repositories: [PAGE_SRC_REPO] contains sources; a regular github repo. [GITHUB_IO_REPO] contains rendered pages Tts name should be_USER_NAME_.github.io, and needs to be public Move to the newly created repository -> ‘Settings’ -> ‘Pages’, then set Source: Deploy from a branch Branch: master / root Create a hugo site mkdir ~/webpages; cd ~/webpages hugo new site hugo_pages Install a theme (as a submodule) Visit https://themes.

I tried to run REMnux VM with the following settings: Macbook pro (M2) Mac OSX Sonoma UTM 4.4.5 (brew installed; brew install --cask utm) Downloaded the REMNux VM (from https://remnux.org/#distro) References https://www.technomancer.com/archives/568 https://www.youtube.com/watch?v=krGvTMq29gA Convert the format of the REMNux disk image $ qemu-img convert -p -f vmdk -O vhdx REMnuxVM.vmdk REMnuxVM.vhdx * -p: indicates the conversion progress. * -f: indicates the source image format. * $ qemu-img convert -p -f vmdk -O qcow2 REMnuxVM.

Install Install a Ubuntu Server version(I installed the minimal Ubuntu 22.04 Server). Use the Shared Folder Ref: https://docs.getutm.app/guest-support/linux/#virtfs on the UTM Menu, “Edit” the configuration of the Ubuntu VM and set up a shared directory with the “VirtFS” (not SPECI WebDAV) create a local directory on the guest $ sudo mkdir /media/share mount $ sudo mount -t 9p -o trans=virtio share /media/share -oversion=9p2000.L
