If which doesn't find it, try a more exhaustive search:
Even with Magisk, some poorly coded apps search only /system/bin/su . Magisk hides its binary behind resetprop and magiskpolicy .
For Termux users, a significant shift occurred with . Following the update, many users found that sudo commands, which previously worked, started failing. This has been linked to a fundamental change: Magisk's core implementation was rewritten in the Rust programming language. This likely altered how the su binary is presented or how the environment's PATH variable is handled by tools like Termux, causing them to lose track of the binary. no superuser binary detected are you rooted new
Sometimes the binary path is broken but still accessible via adb.
| Scenario | Description | |----------|-------------| | | The simplest explanation is that the device has never been rooted—so the su binary simply doesn't exist. | | Root Incomplete | A partial or failed root attempt may have left the su binary in an unconventional location or without proper permissions. | | Path Issue | The su binary exists, but it's located in a directory not included in the shell's PATH environment variable. | | Magisk (or other root) Not Properly Installed | The root management tool (Magisk, SuperSU, etc.) is not correctly installed, leaving the su binary missing entirely. | | SELinux Interference | Security-Enhanced Linux policies may be blocking access to the su binary, even if it is present. | | Zygisk or DenyList Configuration | Magisk's Zygisk or DenyList features may be interfering with root permission requests. | | Outdated Root Checker App | The app checking for root may be using outdated detection methods that don't work with modern root solutions. | If which doesn't find it, try a more
If the app checks for su and cannot find it—or cannot execute it due to permissions—it returns the "No superuser binary detected" error.
: Newer versions of Magisk may store the su binary in non-standard locations like /debug_ramdisk/su instead of /system/bin/su . Following the update, many users found that sudo
Over-the-air (OTA) updates from your carrier often overwrite the boot partition or system partition, erasing any root binaries. The superuser app remains installed, but the binary is gone.

Your manager app (Magisk App) is not updated, or it lost its link to the system.
The error message usually occurs in Termux when wrappers like sudo or tsu cannot locate the su binary. This breakdown happens frequently after updating to recent versions of root managers like Magisk 29+ or Kitsune Mask , where the core implementation shifts or uses systemless paths like /debug_ramdisk/su .
