I have struggled and got the solution. It looks like the problem was with the apktool and also the java environment variables (but in your case it could be only one issue), i uninstalled the apktool & java's(jdk,jre), reinstalled, changed versions through terminal but nothing worked.
FIRST ISSUE (_JAVA_OPTIONS) :
To figure this out i read an issue on github https://github.com/iBotPeaches/Apktool/issues/2325
To temporarily fix it, run the following commands in the same terminal window where you are trying to use msfvenom
:
_SILENT_JAVA_OPTIONS="$_JAVA_OPTIONS"
unset _JAVA_OPTIONS
alias='java "$_SILENT_JAVA_OPTIONS"'
To permanently fix it, place the above commands in /root/.bashrc
(you have to check Show hidden files in View tab).
Now the above error message should go away, and if there is an issue with your apktool it will be displaying unable to rebuild apk with apktool. So, to figure this out read below:
SECOND ISSUE (Apktool)(unable to rebuild apk with apktool):
I have found that there is a missing file
of apktool located in usr/local/sbin
. Delete apktool
file from there if exists.
Download linux wrapper script https://raw.githubusercontent.com/iBotPeaches/Apktool/master/scripts/linux/apktool
Download latest apktool from https://bitbucket.org/iBotPeaches/apktool/downloads and rename it to apktool.jar
Now copy both the files (linux wrapper script & apktool.jar) to /user/local/bin
Type apktool
in terminal and verify the version
