  (Asked by: username_0 on 2024-05-14)
  
  I have tried to install prokka using homebrew using the code `brew install prokka` (I also tried `brew install brewsci/bio/prokka`) and it gave this error:
  
  ```
  curl: (7) Failed to connect to mbio-serv2.mbioekol.lu.se port 80 after 75009 ms: Couldn't connect to server 
  Error: prokka: Failed to download resource "aragorn" 
  Download failed: http://mbio-serv2.mbioekol.lu.se/ARAGORN/Downloads/aragorn1.2.38.tgz
  
  ```
  
  I then tried installing with conda using the code
  
  ```
  conda create -n prokka_env 
  conda activate prokka_env 
  mamba install prokka
  
  ```
  
  and it gave the error:
  
  ```
  Could not solve for environment specs
  The following package could not be installed
  └─ prokka does not exist (perhaps a typo or a missing channel).
  
  ```

  Prokka's github page  [github page](https://github.com/tseemann/prokka) has:
  
  ```
  conda install -c conda-forge -c bioconda -c defaults prokka
  
  ```
  
  **edit**
  
  Seems that there may be another way to do it:
  
  [stepwise components install](https://github.com/tseemann/prokka/issues/615)
