EPROTO 101057795:error:140943F2 Installing Packages under Windows 10 Home on UP Squared


I have just installed Atom on my UP^2 unfortunately when I try to install any new packages I get the following error:

write EPROTO 101057795:error:140943F2:SSL routines:ssl3_read_bytes:sslv3 alert unexpected message:openssl\ssl\s3_pkt.c:1493:SSL alert number 10
101057795:error:1409E0E5:SSL routines:ssl3_write_bytes:ssl handshake failure:openssl\ssl\s3_pkt.c:659:

No packages are shown not even the ones that should have been installed by default.

I have had no problems with the installation on my laptop where I installed the Platformio IDE which I use everyday.


There appears to be a problem with the version of OpenSSL used by Atom for machines using Intel Sky Lake / Apollo Lake CPUs and possibly other recent Intel platforms. I just bought a mini PC with the Celeron J3455 and am seeing this issue when trying to search for packages.
