Hi,

I am a bit stucked. I am using a clean Linux Debian distribution with only qiime1&2 installed according to the [install docs](https://docs.qiime2.org/2017.12/install/native/). There should be no existing R/R Studio installation.

Based on the description in the [.RProfile trick](https://forum.qiime2.org/t/dada2-exit-code-11-and-rprofile/1386/11) I tested the command:

`R -e ".libPaths()"`

This command returned:

```
> .libPaths()
[1] "/home/martin/miniconda3/envs/qiime2-2017.12/lib/R/library"
> 
> 

```

I guess this means that everything is okay and no conflicting R installations should be expected?

I even tried to create an `~/.Rprofile` file, including the line `.libPaths(.libPaths()[1])`.

This didn't changed anything and I still encounter the return code -11 while running DADA2.

Cheers,  
Martin

[EDIT]  
I tried to remove old qiime2 environments (`remove -n qiime2-2017.10`, `remove -n qiime2-2017.11`, `remove -n qiime2-2017.12`, `conda clean -y --all`) and [qiime2 re-installation](https://docs.qiime2.org/2017.12/install/native/), but without any success.
