• TecMint ☛ Netplan: Configure Static IP Address and DNS on Ubuntu 26.04

  For desktop users, Netplan usually works quietly in the background, but on VPS servers, home labs, or remote Ubuntu systems, knowing how to configure static IP addresses, DNS servers, and multiple interfaces becomes very important, because a small YAML mistake can even disconnect your server if you’re working remotely over SSH.

• TecMint ☛ Upgrade Ubuntu 24.04 to Ubuntu 26.04 LTS

  Every failed Ubuntu release upgrade I’ve seen over the years usually came down to one of three things: the system wasn’t fully updated first, an old third-party PPA broke dependency resolution, or the machine wasn’t rebooted after a kernel update. Once those issues are handled, the actual upgrade process becomes much easier.

    Rootless containers make Podman a practical fit on Debian when you want local container builds and test runs without adding a long-running Docker daemon.
