NimbostratusF5 VPN Broken on Ubuntu 18.04 LTS
NimbostratusI've just stumbled upon this issue after a user reported Ubuntu 18.04 (officially released today) wasn't working.
https://support.f5.com/kb/en-us/products/big-ip_ltm/releasenotes/related/relnote-supplement-bigip-13-0-1.htmlA710407-1 identifies that QT 5.10.1 has issues and the "workaround" is to "Install Qt version 5.9.0 or lower, and make it the default installation."
I've not looked on an Ubuntu installation itself but Google suggests Ubuntu 18.04 runs QT 5.9.1 (maybe 5.9.5) so it's a case of nearly but not quite :(
miostreams_1604Ubuntu 18.04 uses QT 5.9.5, however after running into this problem, I downgraded to QT 5.9.1 using the Ubuntu 17.10 repos and the problem is resolved. Not the best solution, but there is indeed something going on with QT.

I've just had an update on this issue from F5 support:
"I discussed this with an escalation engineer who already has a case open with F5 Production development team. As per his case the issue is due to newer distributions of Linux that have QT with hardcoded dependency on OpenSSL. The fix for this bug is that will package Qt with our installation.
What is more, F5 planned to release client 7.1.1 with these fixes in later part of June."
This sounds very promising as, if I've understood correctly, it should resolve QT version related issues across multiple distributions of Linux.

Quick update to say F5 released a new APM Client 2 days ago. I've just installed this and my Ubuntu 18 server was able to connect to the web based VPN (following an upgrade of the local package).
