## sudo failed (exit code 1) when UIF is enabled and devtoolset-8 is installed[¶](https://doc.dataiku.com/dss/latest/user-isolation/troubleshooting.html#sudo-failed-exit-code-1-when-uif-is-enabled-and-devtoolset-8-is-installed "Permalink to this headline")

If devtoolset-8 is installed on your instance and you are using UIF, devtoolset-8 will include a non-compatible sudo in the default PATH. Note that if you recently installed prophet you may encounter this error due to upgrading to devtoolset-8 in order to install the package. If you are using UIF and devtoolset-8 and receive a sudo error, you can force the use of the default sudo with the following steps:

Stop DSS:

§ ./DATADIR/bin/dss stop

Edit your `DATADIR/install.ini` file and add the entry:

§ [mus]

§ custom\_root\_sudo = ["/usr/bin/sudo"]

Start DSS:

§ ./DATADIR/bin/dss start
