Mint upgrading from 18.3 to 19 – Netbeans broke

Seems netbeans cannot work with OpenJDK 10/11 and stops silently shortly after start.

Solution:

uninstall 8.1 from software list and/or remove manual installation from /usr/local

Install OpenJDK 1.8

Download latest 8.2 from netbeans.org.

Install Netbeans 8.2 in current user (aka path /home/youruser). Also install Glassfish/Tomcat in current user. For some reason, installation in /usr/local does fail.

During installation, point your java jdk to /usr/lib/jvm/openjdk-1.8.

Please note that editing the /etc/netbeans.conf file as indicated by some sites is not resolving the issue.

Mint update from 18.3 to 19 – Wine broke

After updating from Linux Mint 18.3 to 19, wine stopped working. This is what was required to correct.

sudo all below commands if required

dpkg --add-architecture i386
apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main'
wget -nc https://dl.winehq.org/wine-builds/Release.key
apt-key add Release.key

Check if you do not have duplicate lines from an earlier install.

vi /etc/apt/sources.list.d/additional-repositories.list

Then the final step.

apt-get update
reboot

apt-get install --install-recommends winehq-stable
