At some point my TorBrowser wouldn't start. When I try it
displays error windows:
Tor unexpectedly exited. This might be due to a bug in Tor itself,
another program in your system, or faulty hardware. ...
Tor exited during startup. This might be due to a bug in your torrc
file or another program on your system, for faulty hardware. ...
I look at the torrc file and it looks like nothing but a set of
harmless links.
My messages log tells me that AppArmor status for torBrowser is
apparmor="DENIED". "denied_mask="r""
So I do # apparmor-status and find six processes are in enforce mode,
including:
/home/haines/.local/share/torbrowser/tbb/x86_64/ \
tor-browser_en-US/Browser/firefox.real
(8708) torbrowser_firefox
I do
$ ps aux | grep 8708
haines 8708 0.1 0.9 2517308 156740 pts/11 Sl 07:53 0:03
./firefox.real --class Tor Browser -profile
TorBrowser/Data/Browser/profile.default
Killing process does not get me torBrowser back.
I gather I could edit the profile in /etc/apparmor.d directly. There
are two profiles there torbrowser.Tor.tor and
torbrowser.Browser.firefox. I didn't know which to edit, and there was
nothing obvious I should do to edit in them.
Instead I simply removed and reinstalled the two profiles with:
# apparmor_parser -R /etc/apparmor.d/<profile>
# apparmor_parser -a /etc/apparmor.d/<profile>
That did not help, so I simply removed them. Then I'm supposed to
inform the kern of this with:
# echo -n “torbrowser.Browser.firefox” >
/sys/kernel/security/apparmor/.remove
Byt get:
-bash: echo: write error: No such file or directory
This is becasue my /sys/kernel/security/apparmor/ directory holds no
.remove file.
I still can't start torbrowser.
I don't want to breask things by going any further such as creating a
.remove file and adding the two lines to it:
torbrowser.Browser.firefox
torBrowser.Tor.tor
