chcem sa spytat, ze ci su balicky instalovane pomocou
dpkg -i napr. pod Ubuntu potom aktualizovane cez apt-get update/upgrade. Alebo sa aktualizuju len aplikacie, ktore su v repozitaroch sources.list? Doteraz som mal pocit ze nie, ale napr. Parallels sa mi zacli aktualizovat tak chcem mat v tom jasno. Dikes!

apt-get updatehladat novsie verzie?update update is used to resynchronize the package index files from their sources. The indexes of available packages are fetched from the location(s) specified in /etc/apt/sources.list. For example, when using a Debian archive, this command retrieves and scans the Packages.gz files, so that information about new and updated packages is available. An update should always be performed before an upgrade or dist-upgrade. Please be aware that the overall progress meter will be incorrect as the size of the package files cannot be known in advance.ak tam balik ale nie je tak sa "rucne" instalovany balik nemoze aktualizovat
