Two days ago my Yoshikoder refused to start on the Ubuntu (GNU/Linux) machine. So I tried in the console
java -jar Yoshikoder-0.6.4.jar and was informed that “Error: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper”. A quick on the web look turned out that the solution is simple. In the console, I opened the following file:
sudo leafpad /etc/java-11-openjdk/accessibility.properties
and commented out the line causing problems (in my case it was the last line), so that it reads:
Trying to do
install.packages("rgdal") on my GNU/Linux machine failed at first. It seems that my system had a couple of libraries not installed, so in the terminal:
sudo apt install libgdal-dev
sudo apt install libproj-dev
install.packages("rgdal") back in R.

My Zotero did not update, showing a dialog that while there is an update available, I apparently lacked the permissions to update. First I tried to chmod the directory where I extracted Zotero to, and the Zotero binary, but that did not change the error message. It turns out there is another directory that needs to be changed:
sudo chmod 707 /usr/bin/zotero && sudo chmod -R 707 /opt/zotero
(in the terminal) and now everything works as it should.
Update 10 April 2019: see comments for a more appropriate handling of the permissions.
Today I noticed Rhythmbox not playing some music files in Debian. After a bit of digging around, I noticed the warning “your gstreamer installation is missing a plugin” in the file properties. From there it wasn’t far to realize that MP3 files did not play in Rhythmbox (any more), and that I probably need a (new) plugin (it’s Debian ‘unstable’ after all, so this was probably introduced by a recent update).
sudo apt install gstreamer1.0-fluendo-mp3 and restarting Rhythmbox was all I needed to do.
The gambit package for Debian (and consequently Ubuntu) is outdated, and not available for up-to-date releases. The website for gambit offers a download for Linux, which can be compiled using the standard
./configure; make; sudo make install.
On my machine, this did not install the GUI. There was actually an explanation on the screen, but I did not read it the first time around: Without the right wxWidgets on the computer, the GUI is simply skipped. The solution: Install
libwxgtk3.0-dev (note the
dev-suffix), and re-install/re-compile gambit.
