## Stuck at Postfix Configuration during Lambda Stack install

Adding `I_AGREE_TO_THE_CUDNN_LICENSE=1` to the top of the installation script does it.

## Lambda Stack seems to be wiped out after Ubuntu update

Hi Mark,
Thanks for the reply. The commands did nothing for me. It looks like the stack was re-installed, but nvidia-smi is not found:

```
ivogeorg@turnaround:~$ sudo rm -f /etc/apt/sources.list.d/{graphics,nvidia,cuda}*; \
COLUMNS=200 dpkg -l |\
awk '/cuda\|lib(accinj64\|cu(blas\|dart\|dnn\|fft\|inj\|pti…
```

## Possibly solved
After fixing [this other error](https://deeptalk.lambda.ai/t/started-getting-tensorflow-profiler-error-after-cuda-update/1676) which was blocking replication of this one, this error has also gone away. It is possible that the software updates shown in the other error description were the solution.

## Started getting TensorFlow profiler error after CUDA update

## Solved
The following worked for me (thanks, Jeremy@Lambda):

In file `/etc/modprobe.d/nvidia-common-kernel.conf`, opened with sudo, write `options nvidia "NVreg_RestrictProfilingToAdminUsers=0"`

Run the command `sudo update-initramfs -u -k all`

Reboot.
