APT-LISTBUGS(1) General Commands Manual APT-LISTBUGS(1)

NAME

apt-listbugs - Lists critical bugs before each APT installation/upgrade

SYNOPSIS

apt-listbugs [options] <command> [arguments]

DESCRIPTION

apt-listbugs is a tool which retrieves bug reports from the Debian Bug Tracking System and lists them. In particular, it is intended to be invoked before each installation or upgrade by APT, or other similar package managers, in order to check whether the installation/upgrade is safe.

USAGE

apt-listbugs [-h] [-v] [-s <severities>] [-T <tags>] [-S <states>] [-B <bug#>] [-D] [-H <hostname>] [-p <port>] [-P <priority>] [-E <title>] [-q] [-C <apt.conf>] [-F] [-y] [-n] [-d] <command> [arguments]

OPTIONS

-h, --help Print usage help and exit.
-v, --version Print version number and exit.
-s <severities>, --severity <severities> Filter (and sort) bugs by severity, showing only the bugs matching specified values. List the bug severities that you want to see, separated by commas and in the desired order. Possible values are "critical", "grave", "serious", "important", "normal", "minor", "wishlist", or the special value "all" to disable filtering. Default: [critical,grave,serious]. The default list may be changed by setting the AptListbugs::Severities configuration option.
-T <tags>, --tag <tags> Filter bugs by tags, showing only the bugs matching _all_ specified values. List the tags that you want to see, separated by commas. Default: no filter. Possible values include "confirmed,l10n" to show only bugs that have both these tags.
-S <states>, --stats <states> Filter (and sort) bugs by pending-state, showing only the bugs matching specified values. List the pending-state categories that you want to see, separated by commas and in the desired order. Default: [pending,forwarded,pending-fixed,fixed,done]. Possible values are:
    pending = open bug
    forwarded = marked as "forwarded"
    pending-fixed = tagged as "pending"
    fixed = tagged as "fixed"
    absent = not found in this distribution/architecture
    done = resolved in some version for this
           distribution/architecture
    
Note that a bug can only match one such state (when multiple conditions on this list match, the later one takes priority), and that "pending" does not mean "tagged as pending".
-B <bug#>, --bugs <bug#> Filter bugs by number, showing only the bugs directly specified. List the bug numbers that you want to see, separated by commas (e.g. "123456,567890,135792"). Default: no filter.
-D, --show-downgrade Show bugs of downgraded packages. (apt mode only)
-H <hostname>, --hostname <hostname> Specifies the hostname of the Debian Bug Tracking System [bugs.debian.org].
-p <port>, --port <port> Specifies the port number of the web interface of the Debian Bug Tracking System [80].
-P <priority>, --pin-priority <priority> Specifies Pin-Priority value [1000].
-E <title>, --title <title> Specifies the title of RSS output.
-q, --quiet Don't display progress bar. This option is assumed if stdout is not a terminal.
-C <apt.conf>, --aptconf <apt.conf> Specifies the APT configuration file to use.
-F, --force-pin When in apt mode, assumes that you want to automatically pin all buggy packages without any prompt. This option is assumed if stdout is not a terminal.
-y, --force-yes Assumes that you select yes for all questions. When in apt mode, this implies that you accept to continue with the installation/upgrade, even when bugs are found or errors occur.
-n, --force-no Assumes that you select no for all questions. When in apt mode, this implies that you want to abort the installation/upgrade, as soon as bugs are found or errors occur. This option is assumed if stdout is not a terminal.
-d, --debug Give extra debug output, important for debugging problems. Please include -d when reporting problems.

COMMANDS


apt
Reads package actions from a file descriptor specified in the APT_HOOK_INFO_FD environment variable (typically provided by APT or other compatible package manager; Pre-Install-Pkgs hook info protocol version 3 is expected - see apt.conf(5) for more details).

list [<package1[:arch][/version]> <package2[:arch][/version]>...]
Reads package names from the arguments and simply lists bugs of these packages. Package versions may be specified with a slash, as in apt/1.0 for example. Package architectures may be specified with a colon, as in apt:amd64 or apt:amd64/1.0 (but please note that the Debian Bug Tracking System does not distinguish the architectures, hence the same bugs will be listed, regardless of the specified architecture).

rss [<package1[:arch][/version]> <package2[:arch][/version]>...]
Reads package names from the arguments and lists bugs of these packages in RSS format. Again, package versions may be specified with a slash and architectures with a colon.

ENVIRONMENT VARIABLES


APT_LISTBUGS_FRONTEND
If this variable is set to "none", apt-listbugs will not execute at all; this might be useful if you would like to script the use of a program that calls apt-listbugs.

http_proxy
If http_proxy is set, the value is used for HTTP Proxy, unless proxy settings are found in APT configuration (see below).

APT_HOOK_INFO_FD
File descriptor from which package actions will be read (APT or other compatible package managers are expected to write information to this file descriptor and to properly set this environment variable).

CONFIGURATION FILE

apt-listbugs understands APT configuration file (see apt.conf). The notable configuration options are

Acquire::HTTP::Proxy
Default HTTP Proxy setting (overrides any http_proxy environment variable value). An empty string or the special keyword 'DIRECT' will disable proxy.

Acquire::HTTP::Proxy::bugs.debian.org
Specific HTTP Proxy setting (overrides the default HTTP Proxy setting). Useful for setting HTTP proxy for apt-listbugs. The special keyword 'DIRECT' will disable proxy.

AptListbugs::Severities
Default (comma-separated) list of bug severities to be shown. When this option is not set, the list is [critical,grave,serious], unless explicitly altered by using the "-s" command-line option. On the other hand, when this option is set, the list of severities is its value, unless explicitly altered by using the "-s" command-line option.

AptListbugs::IgnoreRegexp
Bugs to ignore when in apt mode. This is evaluated using Ruby regular expressions: if the bug title matches, the bug is ignored. Default: nothing. A possible suggested value is "FTBFS", since those bugs tend to not affect the user.

AptListbugs::ParseStep
Maximum number of bug reports to be queried (on the Debian Bug Tracking System) and parsed in a single batch. Default value is 200. The query and parse operation is performed in batches of at most ParseStep bugs, for performance reasons; setting a lower value may slow down apt-listbugs, but may increase reliability on poor network links.

OUTPUT EXAMPLE

    [bug severity] bugs of [package] ([current version] -> [package version to be installed]) <[state of bug report]>
     [bug #] - [bug title] [(Fixed: fixed version, if it's fixed in a future version)]
    
    e.g.
    
    
    Retrieving bug reports... Done
    Parsing Found/Fixed information... Done
    important bugs of apt-listbugs (0.0.47 -> 0.0.49) <Outstanding>
     #332442 - apt-listbugs: Apt-listbugs doesn't actually download any bug reports
     #389903 - apt-listbugs: Does not offer to exit if timeout occurs fetching reports
    Summary:
     apt-listbugs(2 bugs)

EXIT STATUS


0
If the program ran successfully and (when in apt mode) you decided to continue with the installation/upgrade. Or otherwise, if a SIGUSR1 was received (for instance because you issued the command "killall -USR1 apt-listbugs").

1
If an error occurred.

10
If the program ran successfully in apt mode, but you decided to abort the installation/upgrade.

130
If a SIGINT was received (for instance because you pressed [Ctrl+C]).
N.B.: When the program is invoked by APT, any non-zero exit status will cause the installation/upgrade to be aborted.

AUTHORS

apt-listbugs was originally written by Masato Taruishi <taru@debian.org>, and rewritten by Junichi Uekawa <dancer@debian.org> in 2006 to handle BTS Versioning features and the SOAP interface. The --bugs option was added by Francesco Poli <invernomuto@paranoici.org> in 2008. During 2009-2010, apt-listbugs was maintained by Francesco Poli and Ryan Niebur <ryan@debian.org>, then, during 2011-2012, by Francesco Poli and Thomas Mueller <thomas.mueller@tmit.eu>. It is currently maintained by Francesco Poli.
