The Linux Documentation Project maintains an archive of snaphots of the (English language) core Linux manual pages that are maintained by Michael Kerrisk. Corrections and additions are welcome, but review the "Help Wanted" list, first.

Man pages belonging to programs are usually distributed together with those programs. Therefore, the core Linux man-pages mainly contains the pages for system calls and library routines, special devices, and file formats. However, it also contains documentation for a few programs, in cases where the authors or maintainers of the program do not distribute man pages themselves.

This page is part of release 3.11 of the Linux man-pages project. A description of the project, and information about reporting bugs, can be found at

apt-cdrom - APT CDROM management utility


apt-cdrom [-hvrmfan] [-d=cdrom mount point] [-o=config string] [-c=file] [add | ident]


apt-cdrom is used to add a new CDROM to APTs list of available sources. apt-cdrom takes care of determining the structure of the disc as well as correcting for several possible mis-burns and verifying the index files.

It is necessary to use apt-cdrom to add CDs to the APT system, it can‐ not be done by hand. Furthermore each disk in a multi-cd set must be inserted and scanned separately to account for possible mis-burns.

Unless the -h, or --help option is given one of the commands below must be present.

add is used to add a new disc to the source list. It will un‐ mount the CDROM device, prompt for a disk to be inserted and then procceed to scan it and copy the index files. If the disc does not have a proper disk directory you will be prompted for a descriptive title.

APT uses a CDROM ID to track which disc is currently in the drive and maintains a database of these IDs in /var/lib/apt/cdroms.list

ident A debugging tool to report the identity of the current disc as well as the stored file name


All command line options may be set using the configuration file, the descriptions indicate the configuration option to set. For boolean op‐ tions you can override the config file by using something like -f-,--no-f, -f=no or several other variations.

-d, --cdrom
Mount point; specify the location to mount the cdrom. This mount point must be listed in /etc/fstab and properly configured. Con‐ figuration Item: Acquire::cdrom::mount.

-r, --rename
Rename a disc; change the label of a disk or override the disks given label. This option will cause apt-cdrom to prompt for a new label. Configuration Item: APT::CDROM::Rename.

-m, --no-mount
No mounting; prevent apt-cdrom from mounting and unmounting the mount point. Configuration Item: APT::CDROM::NoMount.

-f, --fast
Fast Copy; Assume the package files are valid and do not check every package. This option should be used only if apt-cdrom has been run on this disc before and did not detect any errors. Con‐ figuration Item: APT::CDROM::Fast.

-a, --thorough
Thorough Package Scan; This option may be needed with some old Debian 1.1/1.2 discs that have Package files in strange places. It takes much longer to scan the CD but will pick them all up.

-n, --just-print, --recon, --no-act
No Changes; Do not change the sources.list(5) file and do not write index files. Everything is still checked however. Configu‐ ration Item: APT::CDROM::NoAct.

-h, --help
Show a short usage summary.

-v, --version
Show the program version.

-c, --config-file
Configuration File; Specify a configuration file to use. The program will read the default configuration file and then this configuration file. See apt.conf(5) for syntax information.

-o, --option
Set a Configuration Option; This will set an arbitary configura‐ tion option. The syntax is -o Foo::Bar=bar.
