"UnsatisfiableError" during installation

[YePererva]

Hello! I encountered several errors while installing. Please, help to solve it.

Steps to reproduce:

With manual installation:

1. Install Anaconda 3:

# install anaconda prerequisites
sudo apt install libgl1-mesa-glx libegl1-mesa libxrandr2 libxrandr2 libxss1 libxcursor1 libxcomposite1 libasound2 libxi6 libxtst6
# install anaconsa itself
cd ./Downloads
wget https://repo.anaconda.com/archive/Anaconda3-2020.11-Linux-x86_64.sh
bash ./Anaconda3-2020.11-Linux-x86_64.sh
# allow to install to /home/username/anaconda3
# reject running conda init at start-up of system
# add conda to system $PATH varialbe
export PATH="/home/username/anaconda3/bin:$PATH"

This part works fine. 2. Install prerequisites, as described in README.md file:

# the following line works without problem:
conda install h5py
# the next line returns the 'UnsatisfiableError'
conda install -c bioconda pysam
# the following line works without problem:
conda install -c bioconda edlib
# the next line returns the 'UnsatisfiableError'
conda install -c bioconda python-edlib

The error message for pysam is:

~$ conda install -c bioconda pysam

With DockerFile

1. Installing Docker

sudo apt update && sudo apt upgrade -y
sudo apt install -y apt-transport-https ca-certificates curl gnupg
sudo apt install -y docker-ce docker-ce-cli containerd.io

It works. No error here. 2. following instructions from README.md file:

cd /mnt/d/biotools
wget https://raw.githubusercontent.com/yfukasawa/LongQC/master/Dockerfile
sudo docker build -t longqc .

And the last line raises an error with the following log:

$ sudo docker build -t longqc .

Please, advise the fix.

I'm having the exact same issue on my MAC. A fix would be greatly appreciated.

[yfukasawa]

Hello @YePererva and @Jake-Goodall,

Sorry for late checking but thanks for contacting!! I'm now trying to reproduce the issue, tentatively installing ubuntu20.04 on a VM. I feel this might have been caused by your python version, which could be out of support in pysam and python-edlib. e.g. your python might be a newer one than the ones supported. conda, pysam, and python-elib are all supported by different teams; sometimes this kind of conflict happens.

Can I ask your python version? python --version

Yoshinori

[YePererva]

@yfukasawa, thank you for your responce!

I'm using Python 3.8.5 Is there any other info I should provide?

[yfukasawa]

Hi @YePererva ,

Thank you for sharing python version. I've tried installation on VM using both python3.8 and python3.7, and I could reproduce the issue if I use python3.8. It seems that conda packages of pysam/python-edlib are not compatible with python3.8 yet (not checked their specs carefully, but at least I got the same error).

I'll slightly modify the docker image, but tentative suggestion would be downgrading of your conda python to 3.7 or lower version. conda install python=3.7 then, install other dependencies.

Hope this helps. Yoshinori

Hi @yfukasawa

I was having the same error and found out that it is fixed with python 3.9

I built the following Docker image https://hub.docker.com/repository/docker/grpiccoli/longqc

The Dockerfile is here: https://github.com/grpiccoli/longqc.nf/blob/master/Dockerfile

[yfukasawa]

Hi @grpiccoli,

Many thanks for checking with python 3.9! will update Dockerfile.

Best, Y.

[grpiccoli]

No worries, thank you for this useful tool, I just updated the docker image in dockerhub to be compatible with singularity, nextflow, snakemake and it uses alpine image to save a little space. I'm updating dockerfile as well in case it might be useful Best G

[kim-fehl]

Still getting this error when using file downloaded from the Releases. Has it been updated?

[yfukasawa]

Hi @kim-fehl, thanks for a reminder! Updated the Dockerfile, and it should be available in 1.2.0c. Let me know if this doesn't work for you.

Hello could you please explain some details on how to run it with singularity, I pulled the docker image as a sif file...
