Frequently asked questions ( 5 )

Q

How can I keep my Debian system current?

A

One could simply execute an anonymous ftp call to a Debian archive, then peruse the directories until one finds the desired file, and then fetch it, and finally install it using dpkg. Note that dpkg will install upgrade files in place, even on a running system. Sometimes, a revised package will require the installation of a newly revised version of another package, in which case the installation will fail until/unless the other package is installed.

Q

Are there any on-line resources for discussing Debian?

A

Yes. In fact, the main method of support Debian provides to our users is by the way of e-mail. We'll give some details on that, and mention some other useful resources.

Q

Can I automatically update the system?

A

Yes. You can use cron-apt; this tool updates the system at regular intervals using a cron job. By default, it just updates the package list and downloads new packages, but without installing them.

Q

Do I have to keep all those .deb archive files on my disk?

A

No. If you have downloaded the files to your disk then after you have installed the packages, you can remove them from your system, e.g. by running aptitude clean.

Q

Must I go into single user mode in order to upgrade a package?

A

No. Packages can be upgraded in place, even in running systems. Debian has a start-stop-daemon program that is invoked to stop, then restart running process if necessary during a package upgrade.
