PK-DEBUGINFO-INSTA(1) [FIXME: manual] PK-DEBUGINFO-INSTA(1)
NAME
pk-debuginfo-install - Debugging Packages Installer
SYNOPSIS
pk-debuginfo-install [--help] [--verbose] [--simulate] [--no-depends]
DESCRIPTION
This manual page documents briefly the pk-debuginfo-install command.
pk-debuginfo-install is the command line client for installing debuginfo packages.
WHY DO I NEED DEBUGINFO PACKAGES
?
When a program crashes, it's often useful to send the developer a backtrace which contains symbol names and variable contents, rather than
memory addresses. To make this possible, extra packages called debug packages can be installed.
OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
below.
--help
Show summary of options.
--noninteractive
Do not be interactive and skip the confirmation before the packages are installed.
--verbose
Show extra debugging information.
--simulate
Don't actually install any packages, only simulate what would be installed.
--no-depends
Do not scan for, or install dependencies of the core packages.
--quiet
Do not display information or progress to the terminal.
RETURN VALUES
0
Success, at least one package was installed
1
Failed with miscellaneous internal error.
3
Failed to get software sources list.
4
Failed to enable software sources.
5
Failed as nothing to do.
6
Failed to find dependant packages.
7
Failed to install.
8
Failed to disable software sources.
