= Debian = '''Debian''' is a Linux-based operating system. '''Ubuntu''' is downstream. <> ---- == Branches == The operating system is developed and maintained in branches: * '''Stable''' is the current release and receives periodic updates to software. * '''Oldstable''' is the previous release. It receives only security updates, and even then for just a year. * '''Testing''' is the next release. Kernels and software have been tested but not thoroughly, so both instability and frequent updates should be expected. * '''Unstable''', codenamed '''Sid''', is the active development branch. While it is expected to boot and run, code changes are checked in without testing. * '''Experimental''' is not even expected to boot and run. ---- == Installation == ---- == Administration == * [[Linux/Debian/Apt|apt]] * [[Linux/Systemd|systemd]] ---- CategoryRicottone
