Answer 1

The better approach is to do a cleanup

conda clean --all

Answer 2

The issue is with corrupt openssl package. You need to first delete all openssl pkg files and reinstall them. This is what I did:

# as the error show where the openssl files are
cd  %USERPROFILE%\AppData\Local\Continuum\miniconda3\pkgs\
# with linux I did rm -fr openssl*
DEL /Q /F /S "openssl*"
# install openssl from libarchive
conda install -c conda-forge libarchive

That reinstall openssl and everything will be back to normal.

Answer 3

InvalidArchiveError when trying to install with conda can happen if you don't have enough free space on the hard disk. Make sure you have enough free space.

Answer 4

I had this same problem - I had an IPython instance open that was holding onto the Openssl handle open so I wasn't able to delete the Openssl folder as mentioned above by Prayson. After closing all of my IPython & Python instances through the command prompt, or entering the following in a command prompt:

TASKKILL /F /IM python.exe

I was then able to run

conda install -c conda-forge libarchive

(as mentioned previously) to update the openssl library without having to actually delete anything. After that, everything went back to normal.
