Thank you very much for the info. You made me realize that I can change the jdk version NetBeans runs on, without having to change my local jdk, or the jdk I build projects with.
I downloaded jdk-14 and pointed “netbeans_jdkhome” in netbeans.conf to this jdk-14 distro and now checking for plugins works. I receive no certificate errors, and plugins are installable. So either NB 12 has problems in this area when running on JDK8, or there’s an issue with my local version of JDK8.

My remote situation is just easier if I RDC -- so my fedora workstation runs XRDP. To conserve bandwidth I generally run my rdc client (remmina on F31 laptop) in 16 bit color depth. Many/Most Java/Swing like programs; including NB 10,11,12; running under JDK > 8 would draw empty windows (running on my workstation in xrdp, but displaying on my laptop via remmina; also true in rare cases where I actually use Windows RDC client to my F31 workstation). Anyway, when NB 12 dropped a few weeks ago, I had thought I read somewhere that it would run under JDK 8 but recommended a newer JDK, I even thought there were words somewhere saying JDK14 is recommended. ....so... I fiddled with lots of JAVA_OPTs tweaking gui stuff (gtk, dpiaware, java2d, etc) -- nothing. Long story short, I happened to reconnect to my workstation but UPPED the color depth from 16 to 24bits....and then NB 12 (w/o java_opt tweaks) started to draw using JDK14.... So does NB12 officially run under JDK8 -- no idea. That said, I did observe NB12 running seemingly fine under jdk8 -- but didn't really use that config as a daily driver once I got NB12 + JDK14 rolling ok. FWIW: I routinely run builds from NB12 -- all gradle -- using JDK 8 as a configured JDK platform -- I have a few JDK11 gradle builds too. HTH...

Interesting point about the JDK version you use with NB 12. Does NB 12 support JDK 8? I looked around but don’t see any information on that. Am I missing something obvious?

I am and the DLP I am behind messes with HTTPS traffic and certs. I've had to import a trusted cert at system level (also Fedora 31, but running selinux and firewalld). A few java programs I've run had this problem; just had this with JMeter a week or so ago. I used keytool to import my DLP cert and the issue went away (JDK8). That said, I am running NB 12 under JDK 14, and don't recall this with NB12; when I started using it a couple of weeks ago (and don't' recall importing my DLP cert into my JDK14 install).

I’ve downloaded the latest LTS release this morning. When selecting the ‘Check for Updates’ under Plugins menu I am receiving this error… Unable to connect to the NetBeans Distribution because of sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target The URL https://netbeans.apache.org/nb/updates/12.0/updates.xml.gz under Settings for my “NetBeans Distribution” portal works fine in the browser. I can download the .gz file no problem. The same cert issue occurs with the NetBeans Plugin Portal. My environment: Fedora 31 - SELinux disabled, stopped firewalld java version "1.8.0_45" The only thing I’ve tried, is importing *.apache.org <http://apache.org> .pem certificate into cacerts. Is there a way to gather more information from the exception? I am behind a company firewall, but I figured if the URL worked in the browser then I’d be fine there. Also, checking for updates/plugins works fine in Netbeans 10, and 11.2. Does anyone know what the issue may be? Thank you
