iOS Daemon app will not start (Jailbreak) when Installed it from Cydia

Question

I developed a daemon that is tracking the location as given in the Chris Alvares webpage.

It is working fine if install it through SSH directly to the phone from mac terminal. It's not at all launching if I install the same daemon through Cydia. I am getting the error in the log as

Mar 3 16:07:11 Jailbreak-iPhone-5S installd[51] : 0×100590000 verify_signer_identity: MISValidateSignatureAndCopyInfo failed for /Applications/Myapp.app/TsavoriteClient: 0xe800801c

Mar 3 16:07:11 Jailbreak-iPhone-5S installd[51] : 0×100590000 load_application_info: Failed to validate binary at path /Applications/Myapp.app/Myapp: 0xe800801c. This binary may not work properly.

I tried all steps given in this post.

Any idea what's wrong here?

Answer 1

Finally found the solution after long debugging steps!

The problem is with the LaunchDaemon plist file ownership. If I copy plist from SSH the the file properties are as below

-rw-r--r-- 1 root wheel 461 Mar 3 15:20 com.Mycompany.Myapp.plist

If the LaunchDaemons copied by cydia the file properties are as below

-rw-r--r-- 1 503 staff 461 Mar 3 15:20 com.sourcebits.TsavoriteClient.plist

We need to change the LaunchDaemons plist file ownership before preparing the .deb file using the command

sudo chown -R root:wheel filePath
