FAILED: setup-jack-server when building LineageOS

I'm attempting to build LineageOS for the Moto Z (griffin) on a server, but the build crashes and burns 5 minutes out the gate.

The server is set up for personal use. It has 24GB RAM and 300GB of available storage. I also set up a 20GB swap file in case the Jack server somehow needed more.
The Jack log file reports the follwing:

I've attempted to change the port # in the jack config files, reinstalling jack, resyncing the repo, all to no avail.

I also ran into this problem and it appeared to be BOTH an issue with TLS, guessing the older build was trying to use an obsoleted TLS version, AND a memory issue.
TLS
I followed Error in building android image, fails with jack server:
Edit java.security file under /etc/java-8-openjdk/security/
Remove TLSv1, TLSv1.1 from jdk.tls.disabledAlgorithms
Restart the jack server:
jack-admin kill-server
jack-admin start-server
Memory
NOTE: It's necessary for the build to first fail before running the following steps.
I followed the recommendation here: https://groups.google.com/g/android-building/c/8SQ0-4zZDo8, specifically, I needed to run
export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx7000m"
AND
I modified ~/.jack-server/config.properties:
jack.server.max-service=1
Success
After that I was able to build LineageOS

Quick and dirty fix which bypasses the problem is disabling jack entirely following Yan's answer here. I'm leaving the question open however, since it doesn't actually solve the problem.

1.I made it past this error by adding and editing the following variables before building.
export LC_ALL
2.Edit java.security file under /etc/java-8-openjdk/security/
Remove TLSv1, TLSv1.1 from jdk.tls.disabledAlgorithms
Restart the jack server:
jack-admin kill-server
jack-admin start-server
3.. build/envsetup.sh
4.Run brunch command
brunch lineage_jfltexx-userdebug

I have accidentally uninstalled jack server while building Android AOSP

I am building the Android code for Android Go on my ubuntu 14.04 machine.
While building I got some problems with jack server and I ended up uninstalling the jack server (accidentally).
How do I install the Jack Server again ?
I have tried to install the jack server using the following command:
jack-admin install-server jack-launcher.jar jack-server-4.11.ALPHA.jar
However, I get an error:
Jack server installation not found
Kindly help how do I install Jack Server again.
I have also followed guides from Google Search Result but it has not helped so far.
Update -1
After trying the answer from #gaoc I get the following error each time I try to make the build. :

Show the list of removed packages:
$ awk '$3 == "remove" { print $1, $2, $4 }' /var/log/dpkg.log | tee list
If you can find the removed package in the list, then reinstall:
$ sudo apt-get install --reinstall nameofpackage

Following is the solution that helped me with jack server issue:
Delete ~/.jack-server directory and ~/.jack.settings file. This will be recreated when we run make command, so nothing to worry about that.
Sync repo again using this command (takes about 30-40 minutes):
repo sync -c --no-clone-bundle --no-tags -j4
This -c option with sync command will tell the git about branch you really need instead of all repositories. -jn (-j4 in my case) , here n refers to the number of threads you want.
Now build environment , lunch and make as usual.
I will also share another link to Google Group which has some significant information regarding this issue. : https://issuetracker.google.com/issues/37070263

wpa_supplicant reply to any command with UNKNOWN COMMAND except PING, LIST_NETWORKS, ATTACH, DETACH, TERMINATE, and STATUS?

First of all my target system is android.
I created a c++ application to communicate with wpa_supplicant through the control interface provided as a wpa_ctrl.c file (I included the header file wpa_ctrl.h and linked with the library libwpa_client.so)
here is the documentation page.
Every thing was working fine, but suddenly every command I send is replied by UNKNOWN COMMAND, I suppose that the commands that work fine (ping, list_networks, status, and terminate) have a common thing (maybe they do not need to open the wpa_supplicant.conf which causes the problem on other commands)
here is how I open the connection:
this->ctrl = wpa_ctrl_open(this->socket.c_str());
here is how I send commands:
s = wpa_ctrl_request(this->ctrl, cmd.c_str(), cmd.length(), this->_reply, &reply_len, msg_cb);
above method signatures:
struct wpa_ctrl * wpa_ctrl_open(const char *ctrl_path);
int wpa_ctrl_request(struct wpa_ctrl *ctrl, const char *cmd, size_t cmd_len,
char *reply, size_t *reply_len,
void (*msg_cb)(char *msg, size_t len));
example output:
PING
PONG
UNKNOWN COMMAND: MIB
UNKNOWN COMMAND: STATUS-VERBOSE
UNKNOWN COMMAND: PMKSA
UNKNOWN COMMAND: LOGON
UNKNOWN COMMAND: LOGOFF
UNKNOWN COMMAND: REASSOCIATE
UNKNOWN COMMAND: RECONNECT

Here is a screenshot of an older version of the program working almost fine:
any help is appreciated.
EDIT: I tested the program on my other device and it worked well. But still broken on my main device, probably a factory reset will solve it. But I still want to know the cause of the problem.

The problem was that the interface name was wrong.

Function: selinux_android_load_priority [0], There is no sepolicy file

I have 2 errors in logcat.
Function: selinux_android_load_priority [0], There is no sepolicy file
04-11 10:58:13.837: E/SELinux(10101): Function: selinux_android_load_priority , loading version is VE=SEPF_SGH-I337M_4.3_0022
It's not fatal, my app seems to be fine.
Any idea what is the cause, and how do I fix it? Just can have Error Logs in my app!

I don't know how to get rid of those messages. But they do prevent the Android NDK ndk-gdb script from working. I found this question while searching for a way to get the debugger working after getting this error:
ERROR: Could not setup network redirection to gdbserver?
Maybe using --port=<port> to use a different TCP port might help?
This seems to be an issue with some phones - possibly Samsung phones, or at least the one that I am working with is a Samsung Galaxy Note 2. Certain commands (such as run-as) come with these selinux warning messages in stderr output.
The ndk-gdb script parses output from shell commands run on a device to determine facts like the path of the data directory for the package that it is debugging. The selinux messages interfere with that collection. To fix that problem, edit $NDK_HOME/ndk-gdb and make this change:
diff --git a/ndk-gdb b/ndk-gdb
index 537808e..c8561e5 100755
--- a/ndk-gdb
+++ b/ndk-gdb
## -620,7 +620,7 ## else
fi
# Find the <dataDir> of the package on the device
-adb_var_shell2 DATA_DIR run-as $PACKAGE_NAME /system/bin/sh -c pwd
+adb_var_shell DATA_DIR "run-as $PACKAGE_NAME /system/bin/sh -c pwd 2>/dev/null"
if [ $? != 0 -o -z "$DATA_DIR" ] ; then
echo "ERROR: Could not extract package's data directory. Are you sure that"
echo " your installed application is debuggable?"

android monkey runner scripts

I was trying to run a a sample python program using monkey runner but unfortunately throwing an error of this type :
Can't open specified script file
Usage: monkeyrunner [options] SCRIPT_FILE
-s MonkeyServer IP Address.
-p MonkeyServer TCP Port.
-v MonkeyServer Logging level (ALL, FINEST, FINER, FINE, CONFIG, INFO, WARNING, SEVERE, OFF)
Exception in thread "main" java.lang.NullPointerException
so any one can guide me how to resolve this and how to use monkey runner to execute this type of things

I've found that making the path to the script absolute helped monkeyrunner.
I am invoking the runner from a Python script where a helper class has a startMonkey method:
def startMonkey(self, monkeyScript):
command = [ self.env + '\\tools\\monkeyrunner.bat' ]
command.append( os.path.abspath( monkeyScript ) )
return startProcess( command )
This seems to be working for me.

Script file should be a full path file name try below monkeyrunner c:\test_script\first.py
So go to the folder \ sdk \ tools
and press shift and right click to open command prompt and type monkeyrunner c:\test_script\python_file_name.py
