UPDATE-TORBROWSER(1)

NAME
update-torbrowser - Tor Browser Updater by Whonix developers

SYNOPSIS
update-torbrowser [option(s)]

DESCRIPTION
Lets you safely download the Tor Browser Bundle (TBB) from The Tor Project's (TPO) website. It enforces TLS encryption (https) for TPO's website, downloads TBB from the TPO's website, and uses OpenPGP verification.

Default action when no options are given is to perform an update check and ask how you want to proceed.

OPTIONS

•   --alpha

    Download alpha version instead.

•   --onion

    Download from Tor Project's onion rather than clearnet domain.

•   --ordinary

    Uses curl's ordinary progress bar. Only affects progress reporting.

    When using this option, the GUI progress bar will be stuck but downloading will still work. Note, when using this option, it wouldn't notice if the download server were to run an endless data attack, for example the server claiming to provide a 500000 GB big file.

    (It does not use /usr/libexec/helper-scripts/curl-prgrss CURL_PRGRS_MAX_FILE_SIZE_BYTES.)

    However, it can be compensated by either manually terminating update-torbrowser or by using the timeout utility as in the example below.

•   --only-if-newer

    Do not download the Tor Browser when it is already up-to-date.

•   --noask

    Do not ask any questions. Proceed without user interaction. Also sets input method to --input none.

•   --noaskstart

    Do not ask if Tor Browser should be started after update was completed.

•   --nokilltb

    Advanced users only. Do not kill all eventually still running instances of Tor Browser. Useful in case you want to update ~/.tb/tor-browser, while still using ~/tor-browser_something_else.

•   --no-tor-con-check

    Skip Tor bootstrap connectivity check. (Only relevant in anonymity distributions.)

•   --input input

    What to use as input method.

    --input stdin or --input gui or --input none

    When run in command line, by default, standard input (--input stdin) will be used. When using (--input gui), questions will be asked in the graphical user environment. When using (--input none), no questions will be asked.

•   --resume

    Resume previous download.

•   --reset

    Advanced users only. Hard reset. Do not re-download Tor Browser but only overwrite (delete and re-install) Tor Browser. This feature is not designed to fix Tor Browser issues. When running this program normally without --reset it does download and overwrite Tor Browser. There is no additional benefit from using --reset.

BUGS
This script may break when the file name or RecommendedTBBVersions format changes or when upstream makes other changes to the start process or proxy settings detection method.

In this case, Whonix developers will try to provide a fix as fast as possible. Please check Whonix News Blogs, Whonix Forum for a fix or workaround.

In the meanwhile you can also try the instructions for manually updating Tor Browser in Whonix: https://www.whonix.org/wiki/Tor_Browser/Manual_Download

PORTING
This script is currently only tested in Whonix. It could be easily made to work in Tails or on any Linux.
