They probably can't help you if you don't investigate logfiles (it's an alpha release). Please verify /var/log/syslog and copy-paste result here.

I assume you're "stuck" in same situation than me. If so, you probably have something like this in your logfiles:

  • Mar 23 01:34:05 subgraph kernel: [ 665.842249] PAX: execution attempt in: , 323fc950000-323fc960000 323fc950000
  • Mar 23 01:34:05 subgraph kernel: [ 665.842255] PAX: terminating task: /home/user/.local/share/torbrowser/tbb/x86_64/tor-browser_fr/Browser/firefox(firefox):2731, uid/euid: 1000/1000, PC: 00000323fc9506e0, SP: 000003942c471628

To solve (not really, it's probably less secure) this problem, you have to disable pax protection for memory mapping (MPROTECT). Try: setfattr -n user.pax.flags -v "m" PROGRAM_PATH with PROGRAM_PATH refer to the path of firefox on your system. Here: /home/user/.local/share/torbrowser/tbb/x86_64/tor-browser_fr/Browser/firefox

Also, you can use the paxrat tool configuration file. See https://github.com/subgraph/paxrat You can find reference for various paxflags in man paxctl.

If your problem is a different one, just ignore this message.

EDIT: setting pax flags with setfattr or with paxctl depend of your system. Again, see paxrat (you probably want to use setfattr if your system support extended file attributes). Troubleshooting section => https://subgraph.com/sgos/download/notes/index.en.html

As pointed out by @0x6A6F7368 this is most likely due to the ionotify hook in paxrat not setting the pax flag on the torbrowser. It is a known issue ( #54 ) which can be solved by running sudo paxrat -c /etc/paxrat/paxrat_tbl.conf inside a terminal after the TBB installation has completed as described in the caveats notes. This issue will go away completely once TBB is properly packaged ( #18 ).

If this fix doesn't work please come back, ideally with a copy of the /var/lib/oz-daemon.log and dmesg.

A related issue I've run into is that there's a sometimes a broken oz container left over that torbrowser won't start up happily within:

No more information from requester, I'm closing this ticket.

@willscott what you are describing is a different but known problem. I opened a ticket for this particular issue: https://github.com/subgraph/oz/issues/55
