Hmm, weird, because the Ubuntu setup tends to be pretty stable...

Just to doublecheck, can you perhaps make sure that all dependencies are present, by copy+pasting these commands:

sudo apt-get update

sudo apt-get install -y tcsh xfonts-base libssl-dev       \
                        python-is-python3                 \
                        python3-matplotlib python3-numpy  \
                        gsl-bin netpbm gnome-tweak-tool   \
                        libjpeg62 xvfb xterm vim curl     \
                        gedit evince eog                  \
                        libglu1-mesa-dev libglw1-mesa     \
                        libxm4 build-essential            \
                        libcurl4-openssl-dev libxml2-dev  \
                        libgfortran-8-dev libgomp1        \
                        gnome-terminal nautilus           \
                        gnome-icon-theme-symbolic         \
                        firefox xfonts-100dpi             \
                        r-base-dev cmake                  \
                        libgdal-dev libopenblas-dev       \
                        libnode-dev libudunits2-dev       \
                        libgfortran4
