Alebo ako som si updatoval operačný systém. (Nie upgrade na novšiu verziu)
1. Zistíme, či máme vôbec voľné miesto:
root@guliverkel:/home/martin# df -h /dev/sda3
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 15G 3.9G 11G 27% /
2. Zálohujem si grub
root@guliverkel:/home/martin# mkdir /media/data2/grub
root@guliverkel:/home/martin# cp /boot/grub/grub.cfg /media/data2/grub
root@guliverkel:/home/martin# ls -lh /media/data2/grub
total 12K
-r--r--r-- 1 root root 12K Dec 17 08:08 grub.cfg
3. Pozriem sa na to, akú konkrétnu verziu Debianu mám, plus aké mám jadro:
root@guliverkel:/home/martin# cat /etc/*release
PRETTY_NAME="Debian GNU/Linux 9 (stretch)"
NAME="Debian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"
root@guliverkel:/home/martin# uname -r
4.9.0-8-amd64
4. Môžem spustiť prvý krok updatu (apt-get update) alebo v týchto novších verziách stačí apt update
root@guliverkel:/home/martin# apt update
