Failed to sign APK package. (Unity 2017.2.0f3)

Unity Engine

I have made a huge research for resolving this problem and there are two topics just like mine in unity answers but these two can’t also resolve my problem. I tried to set Build System to Gradle, updated sdk, downgraded sdk also did the same for jdk, changed tools folder, put some folders from build-tools to tools I even researched problem as a java error but NO! non of them has resolved my problem. That’s why I’m opening a new question for this issue. Hope somebody can help.

Here it’s my error log:

CommandInvokationFailure: Failed to sign APK package.

It seems
2017.2.0f3 is a real pain in the ass. Try purge it with .deb file: sudo dpkg --purge unity-editor. Then try install it via Official Installer:
2017.3.0b1: http://beta.unity3d.com/download/2ca68d182788/public_download.html
So, here’s how it works:

  • Get the download assistant

  • Make it executable, via your file manager or the command line (chmod +x UnitySetup-2017.3.0b1)

  • Run it, via your file manager or the command line (./UnitySetup-2017.3.0b1)

  • Follow the prompts

The dependencies for the download assistant are:

  • gtk2 (libgtk2.0-0)

  • libsoup (libsoup2.4-1)

  • libarchive (libarchive13) (with support for xar, cpio, tar, gzip, and xz)
