Linux

I ran into this error today while running a python program in Kubuntu 18.04 (upgraded from 17.10):

followed by a bunch of other similar SSL-related errors. When I checked apt, I found that my openSSL install was fine. A generous guy on IRC informed me that I was very likely missing libraries that the app was looking for. S/he asked me to try installing libssl1.0-dev and voila, it worked.

So I had to upload an SVG flowchart which looked great on my computer. However, when accessed from the server, certain text elements were displayed as large black boxes. This was happening only with converted PNGs of the SVG as the SVG itself rendered just fine. I initially thought that this was some kinda font issue. But apparently not. This happens because Inkscape's SVGs are not always valid and in this case, uses something called a flowRoot element which is not valid SVG.

I just ran into the following error while trying to commit (a previously working project) in Eclipse Neon:

So, I've started plugging my headphone into my monitor's headphone jack rather than the analog audio ports in my CPU and there's been a drastic reduction in the volume levels. The volume is often insufficient even when everything in my volume settings is maxed out. Here are a couple of things to try out in KDE/Kubuntu/Linux that might help alleviate the situation.

Today, I started dabbling in doing some screen recording in Linux and while I could find programs to record the screen, I couldn't get the audio working as I wanted. By default, the programs record either the system audio, or the mic audio (or if the program is shit, neither); they don't record both the system audio and the mic audio. The fix for this on my Kubuntu 16.04 (Xenial) system which uses the Pulseaudio system to manage audio is as follows:

So I've been having trouble getting a Windows program to work in Wine (Windows emulator) on my Kubuntu 16.04 system. It's a simple program but one that requires .NET 3.5. Considering its simplicity, I thought that it'd work fine using just Mono and it did fire up. However, it wasn't terribly usable throwing constant errors and being very buggy. So I had to also install .NET 3.5.

On a fresh Debian 8 (Jessie) install, I found that I couldn't update the package repository using apt because security.debian.org was always timing out. While I initially thought this was because of a mirroring issue oslt, it turns out that it's because I was trying to access it via the IPV6 that my VPS was using. Turns out that the fix is reasonably straightforward. You simply tell apt not to bother with ipv6 and simply use ipv4 … like so:

echo 'Acquire::ForceIPv4 "true";' >> /etc/apt/apt.conf.d/99force-ipv4

Edit: Skip this and scroll down for a proper fix!

Just tried installing MongoDB support for PHP on Kubuntu 15.10 via pecl and ran into the following error message which caused the installation to fail:

While this can probably be fixed using some magickery, in my case, I did not want SSL support on a dev server. I just wanted to get the fucker up and running. To this end, I discovered that the issue was that I was using:
