You didn’t mention it so I asume that you can open a shell, did you tried creating a file in the destiny? Also SELinux may be the problem, try temporary disable it, if works, enable it and create an exception. Other thing; since adb daemon runs on 127.0.0.1:5073/TCP check if you have any localhost firewall rules, but this doesn’t make sense if you can open a shell. Last things, download the lastest SDK, you don’t need to install it, just call adb with the full path.

Would you mind sharing some details? computer OS name and version, your adb version and if you installed systemwide or if you compiled/downloaded out of your repos

Did you tried running adb push with sudo? Do a kill-server before
