To get it to show up in the sound menu, I used <code>xfce4-settings-editor<\/code>. Find channel &#8216;xfce4-panel&#8217;, and then the plugin for &#8216;pulseaudio&#8217;, then edit the &#8216;mpris-players&#8217; string to the name of your preferred player.<\/li>\n<li>I use a bunch of ethernet aliases (ie a bunch of IP addresses on the same interface). In 16.04, you could do this through <code>\/etc\/network\/interfaces<\/code>, but in 18.04, you have to do it via <code>\/etc\/netplan\/<\/code>. At first, I tried to do it with vlans, but that does not allow traffic to flow without communicating with a switch\/router. So, basically useless for my purposes (testing and debugging devices with various subnets). My default install came with <code>\/etc\/netplan\/01-network-manager-all.yml<\/code>. I didn&#8217;t have much luck creating a different file name. So I just modified the existing file:<br \/>\nnetwork:<\/p>\n<pre>version: 2\n\u00a0 renderer: NetworkManager\n\u00a0 ethernets:\n    eth0:\n     dhcp4: no\n     dhcp6: no\n     addresses: [192.168.1.10\/24, 192.168.44.6\/24, 192.168.2.10\/24, 192.168.221.143\/24, 192.168.160.6\/24]\n    eth1:\n     dhcp4: no\n     dhcp6: no\n     addresses: [10.7.56.252\/26]\n     gateway4: 10.8.246.193\n     nameservers:\n       addresses: [8.8.8.8, 8.8.4.4, 10.7.132.21, 10.1.184.22]<\/pre>\n<\/li>\n<li>I&#8217;m not up todate with the times. I&#8217;m a bit of a luddite. Whatever. I use openssl to encrypt files, and I have a plugin script for vim that automatically prompts for passwords and does the encrypt\/decrypt on write\/read actions. However, Ubuntu 16.04 uses openssl 1.0.2 and ubuntu 18.04 uses openssl 1.1.0. They are not compatible. Uggh. However 18.04 has a package <code>openssl1.0<\/code>.<br \/>\nSo, my workaround looks like:<\/p>\n<ul>\n<li style=\"list-style-type: none\">\n<ul>\n<li><code>sudo apt install openssl1.0<\/code><\/li>\n<li><code>sudo ln -s \/usr\/lib\/ssl1.0\/openssl \/usr\/bin\/openssl1<\/code><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>Modify my vim script to check for <code>openssl1<\/code> in the path, and use it if available<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>The crux of the openssl difference seems to be in how the key and IV are created from a password. If I use the same Key and IV arguments in both versions, I get compatible\/identical results.<\/p>\n<p>I&#8217;m sure that the openssl workaround is going to bite me soon. Probably once I upgrade macports at home, to coincide with my recent update to Mac OS High Sierra.<\/p>\n<p>Those are the things that I&#8217;ve gotten to so far. I haven&#8217;t gotten around to any of the wine stuff or installing Xilinx tools, etc.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>At first it was painless. Then, yuck.
