I want to know, if I can check the integrity of a downloaded package through FTP and not apt-get. - For if a check sum comes w/ the package - then I can not trust it. If the sums come apart, then, can I: . download and install the package; . trustworthy run debsums for every package to a check sum filed DVD - to know that the packages are safe? -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
