HipChat4 broken after moving to 18.04

Long story super short 'YAY I HAVE NEW MONITORS!' / 'BOO I HAVE TO REINSTALL!" ... HipChat4 what have you done to me? So yeah - handily pretty much the release day for Bionic Beaver (I know right?) 18.04. Work machine - so need to be up on my feet as fast as humanly possible - backups - sweet as - just need tools. HipChat - last time it was the graphics issue - this time it would appear to be shiny new OpenSSL. The fix for me is below - however, my first encounter with this joy showed "Unable access hipchat.com. Please check that your network is connected and try again" .... needless to say, my network was very connected. Much packets. Many wow.

$ nslookup hipchat.com
Server: 127.0.0.53
Address: 127.0.0.53#53

Non-authoritative answer:

Address: 52.23.0.68

So - clutching at straws I ran it from the command line and ran with what it was ACTUALLY complaining about. Here is an abstract:

Warning: [12:31:04][qt.network.ssl][:0] QSslSocket: cannot call unresolved function SSLv23_client_method
Warning: [12:31:04][qt.network.ssl][:0] QSslSocket: cannot call unresolved function SSL_library_init
[12:31:04][void AbstractOnlineStatus::handleReplyFinished(QNetworkReply*):131] errors from onlineStatusCheck found. ErrorStr = "Error creating SSL context (error:140A90C4:SSL routines:func(169):reason(196))"

Okay - a smoking gun - and something is better than nothing.

Atlassian sites seemed to cross-reference a bunch however my trail ended with:

https://community.atlassian.com/t5/Hipchat-questions/hipchat4-openssl-error/qaq-p/146012

- then -

https://jira.atlassian.com/browse/HCPUB-6249

Okay - everyone likes a little false hope. From there

$ sudo bash

# rm /opt/HipChat4/lib/libcrypto.so*

# ln -s /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 /opt/HipChat4/lib/libcrypto.so.1.0.0

# ln -s /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 /opt/HipChat4/lib/libssl.so.1.0.0

Ensure that the application was dead, start from console - and watch it rattle on through all the way to the login prompt.

Happy days indeed.

Thank you unnamed chap/ess... the hero we deserve.
