Bug description

Hi, noob here trying to get my Evernote notes into Notion. Managed to do all the steps except the "brew install enex2notion" step which threw up this error:
Trying a mirror...

Did I do something wrong? Would love to know how to get this installed! (Please explain simply, sorry! I'm amazed I got this far following the instructions to be honest!) Thank you!

You did nothing wrong, the problem is on the homebrew side here. Was there anything else in the log before Trying a mirror...? It may be just a temporary hiccup.

curl: (60) SSL certificate problem: Invalid certificate chain
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

I just tried installing it again, and got the same error sadly!

I think you are getting SSL errors because your OS version is very old and you are not receiving SSL updates anymore. You can try running this before brew install command to avoid SSL checks altogether:

echo "--insecure" > ~/.curlrc
export HOMEBREW_CURLRC=1

Thank you!! Yes I just discovered last night that my OS is... ancient! I tried what you suggested and managed to get a lot further! Yay! THANK YOU! Then I encountered this:

Maybe I didn't follow the instructions correctly? In the meantime, I'll go shop on Amazon for a new laptop!!

[vzhd1701]

You got another error during the installation. Homebrew usually supports only the three most recent versions of macOS, so you're out of luck here. I think you should try using the pre-compiled binary instead of installing it via homebrew.

[rusalki]

Thank you! I really appreciate your help here. I will give that ago and if that doesn't work, I'll either get a new laptop (which I should anyway) or just pay for Evernote premium until I do! Thank you again!!
