What happened?

Dear heldesk,

I used the following steps to install ciao, an x-ray data reduction package used in astronomy:

conda create -n ciao-4.15 \ -c https://cxc.cfa.harvard.edu/conda/ciao \ -c conda-forge \ ciao sherpa ds9 ciao-contrib caldb marx astropy python=3.10

I'm having problems installing ciao from the conda method, the following error messages appear:

CondaError: Downloaded bytes did not match Content-Length url: https://cxc.cfa.harvard.edu/conda/ciao/noarch/caldb_main-4.10.4-0.tar.bz2 target_path: /home/gabriel/miniconda3/pkgs/caldb_main-4.10.4-0.tar.bz2 Content-Length: 2131132070  downloaded bytes: 275348
