The article explains how the dd command can create bootable USB drives from ISO files by writing raw data block by block and thus producing exact disk copies. It guides readers through finding the right device path with tools such as fdisk or lsblk, unmounting any partitions to avoid accidental overwrites, and then running dd with a 4 MB block size, progress status, and fsync for safety and speed. The writer stresses that interrupting the process can leave a corrupted drive, recommends verifying the result with testdisk or SHA‑256 checksums, and cautions about the lack of capacity checking in dd. While noting that user-friendly tools exist for most users, it advises reserving dd for situations where precise binary fidelity is required and urges double-checking image size against device capacity to prevent data loss.
When APT starts complaining that a signing key has expired, the root cause is usually an old GPG key lingering in /etc/apt/trusted.gpg.d. You can spot which keys are past due by running “sudo apt-key list” and grepping for expires or expired to note their fingerprints. Removing the key is straightforward: if you still have apt‑key, delete it with “sudo apt-key del ”; on newer systems replace the source line’s signed‑by reference to a fresh key file and then remove the obsolete one. After cleaning any remnants, run “sudo apt update” and the warning will vanish—essentially just list expired keys, delete them, adjust repository entries, and refresh APT.
