[Pkg-anonymity-tools] Bug#758935: Bug#758935: torbrowser-launcher: fails to start: exit code 127

[Daniel González Gasull]

Hi Holger.

I didn't see anything in the output from the terminal that could help
investigate the issue.  It just says that the I'm running the latest
version.  I thought the exit code 127 would be the most informative
part.

Here is the output from the command line:

$ torbrowser-launcher

As you can see, it doesn't display any error in the terminal.

Now I used ipdb in torbrowser-launcher to see what was exactly happening:

ipdb> n
> /usr/bin/torbrowser-launcher(1064)run()
   1063         devnull = open('/dev/null', 'w')
-> 1064         subprocess.Popen([self.common.paths['tbb']['start']],
stdout=devnull, stderr=devnull)
   1065

ipdb> self.common.paths['tbb']['start']
'/home/gasull/.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/start-tor-browser'


Now running start-tor-browser from the command line:

$ /home/gasull/.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/start-tor-browser
/home/gasull/.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/start-tor-browser:

./Browser/firefox: not found
Tor Browser exited abnormally.  Exit code: 127


Researching a bit more.  Does Browser/firefox exist?  Yes:

$ find .local/ -name Browser
.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/Data/Browser
.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/Browser
.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/Browser/TorBrowser/Data/Browser
$ ls -l .local/share/torbrowser/tbb/x86_64/tor-browser_en-US/Browser/firefox
-rwx------ 1 gasull gasull 100640 Dec 31  1999
.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/Browser/firefox


So, what is happening in line 213 of start-tor-browser?  This:

   210    SYSARCHITECTURE=$(getconf LONG_BIT)
   211    TORARCHITECTURE=$(expr "$(file Tor/tor)" : '.*ELF \([[:digit:]]*\)')
   212
   213    if [ $SYSARCHITECTURE -ne $TORARCHITECTURE ]; then
   214       complain "Wrong architecture? 32-bit vs. 64-bit."
   215       exit 1
   216    fi

So I modify it to print the values of SYSARCHITECTURE and TORARCHITECTURE:

   210    SYSARCHITECTURE=$(getconf LONG_BIT)
   211    TORARCHITECTURE=$(expr "$(file Tor/tor)" : '.*ELF \([[:digit:]]*\)')
   212
   213    echo $SYSARCHITECTURE
   214    echo $TORARCHITECTURE
   215
   216    if [ $SYSARCHITECTURE -ne $TORARCHITECTURE ]; then
   217       complain "Wrong architecture? 32-bit vs. 64-bit."
   218       exit 1
   219    fi

And then I get this:

$ /home/gasull/.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/start-tor-browser
64

/home/gasull/.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/start-tor-browser:
216: [: -ne: argument expected

Launching Tor Browser Bundle for Linux in

234: /home/gasull/.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/start-tor-browser:
./Browser/firefox: not found
Tor Browser exited abnormally.  Exit code: 127


So TORARCHITECTURE is empty, that's why it fails.

How do we proceed from here?

Thank you.
