Following the excellent tutorial from Michel I was able to install PicaSim on Pop! Os and it works great. Very smooth and no lag whatsoever. So I thought if it will work on this machine on Pop! Os then it should work fine on Zorin 16 on this same machine. However after I deleted Wine from the software store and tried to reinstall it using the command line Michel gave I get the following error:
As you can see it says I can't download from that repository securely. So I am at a loss as to what to do to fix that. Thanks for any help anyone can give.
