Hi all, I am trying to install ASPECT on the cluster (CentOS 6.7). I have already downloaded it and run it properly on my workstation. But somehow I have failed to install deal\_ii on the cluster. I am using ‘candi’ to do the installation. I already installed the pre-required dependencies but the compilation of deal\_ii end up with an error highlighted bellow- "This is candi (compile and install) Project: deal.II-toolchain: Found configuration. using (user-forced) ./deal.II-toolchain/platforms/supported/centos7.platform.

You may want to be sure you can access internet from the cluster. I had to specify the http\_proxy and https\_proxy on the cluster in my institution to allow git clone to work! Everything should work fine when you can clone things. In case you can’t clone, then I believe you can download things from github and put them on your cluster with rsync or scp and start by specifying where they are. Best Marine ---

Adding to Marine’s suggestion (see if `git clone https://github.com/dealii/dealii.git` works if you do it manually anywhere on your cluster), I see two funny spaces in the first line (`un pack`) and last line (`deal.II-v9.0 .0`) of your posted output. If those are not just copy-paste artifacts and they actually exist in your output you will want to check how they got there (e.g. accidentally placing them in the installation path argument of candi or in candi.cfg). > [@Joy](#): > > Initialized empty Git repository in /source/candi-master/deal.ii-candi/tmp/unpac k/deal.II-v9.0.0/.git/ > error: while accessing [https://github.com/dealii/dealii.git/info/refs](https://github.com/dealii/dealii.git/info/refs) > > fatal: HTTP request failed > Failure with exit status: 128 > Exit message: candi: git clone [GitHub - dealii/dealii: The development repository for the deal.II finite element library.](https://github.com/dealii/dealii.git) deal.II-v9.0 .0 failed" Hope that helps.

Hi Marine, Thank you for you information. I can access internet from the cluster. The issue might have appeared due to those proxy issues. I have asked my university to specify my proxy on the cluster. I will try to install it . Hope this time it will work! Best Joy ---

Hi Rene, Yes, Those are copy-paste artifacts. I have checked the output. It seems okay. Best Joy
