Migrate Debian Buster (10) APT to Archive
The following script replaces repository URLs to allow installation of apps on this legacy Debian version.
sed -i \
-e 's|deb.debian.org/debian-security|archive.debian.org/debian-security|g' \
-e 's|deb.debian.org/debian|archive.debian.org/debian|g' \
/etc/apt/sources.listDownload Gravatar image from CLI
First you need to compute hash of your e-mail.
echo -n "[email protected]" | sha256sumThan you can download it using curl. Replace HASH with the output from the previous command.
curl -fL "https://www.gravatar.com/avatar/HASH?s=500&d=404" -o avatar.jpgParameters
s=500(Gravatar supports 1–2048px size)d=404(If there is no image return HTTP 404)r=pg|r|x(To change rating)
See more information on Gravatar docs.
Fetch hardware info from CLI
Neofetch is no longer supported, but there is actively maintened alternative called fastfetch for fetching system information and displaying it in a visually appealing way.
sudo pacman -S fastfetch
Replace text in multiple files
Using find and sed a text in multiple files can be replaced using a one liner. If you have GIT bash you can do it in Windows too.
In the example below address of old.server.com will be replaced with new.server.com in all Web.config files.
find /c/inetpub/wwwroot -name "Web.config" -exec sed -i 's/old.server.com/new.server.com/g' {} +Upgrade Debian 11 to Debian 12
I use those steps on LXC virtual in Proxmox:
- Make sure all packages are upgraded:
apt update && apt upgrade - Backup container in Proxmox
- Edit release version:
sed -i'.bak' 's/bullseye/bookworm/g' /etc/apt/sources.list - Update other configuration files in
/etc/apt/sources.list.d/appropriately - Update packages index:
apt update - Do minimal system upgrade:
apt upgrade --without-new-pkgs - Do full upgrade:
apt full-upgrade - Restart the system:
reboot

Yubikey FIDO2 SSH and MacOS
Even on MacOS Sequoia ssh does not support FIDO2. You need to install openssh using brew, otherwise you may get error Cannot download keys without provider when you try to import resident keys from Yubikey using ssh-keygen -K.
After you install openssh brew install openssh, restart terminal and make sure which ssh displays /opt/homebrew/bin/ssh.
Another problem that you may face, which is not related to MacOS is error Provider "internal" returned failure -1. The problem is that you may generate SSH key on Yubikey without FIDO PIN. But if you do not set FIDO PIN, you cannot import the key. Fortunately you can set the PIN later.
