Hi
The switch to XUbunutu 20.04 may mean a switch to Pango > 1.44 (it does
on Ubuntu 20.04), which means loss of support for Type 1 fonts (on
Cairo-based graphics devices).
The Courier fonts (the default for "mono" on Cairo-based devices) that
you found are all Type 1 (.pfb) fonts.
What does this give you (the matches for the default "sans" and "serif"
on Cairo-based devices) ... ?
fc-match Times
fc-match Helvetica
If those are .ttf or .otf fonts then that would explain why "sans" and
"serif" still work.
A workaround is to specify the family name for a non-Type-1 monospaced
font, e.g., "Courier New" (?), or install a non-Type-1 Courier
replacement (and specify that).
Hope that helps.

Hi all,
On my system (Xubuntu 20.04), using par(family="mono") is not rendered
correctly. The same issue was raised here:

<https://stackoverflow.com/questions/64207220/rendering-plot-in-r-with-mono-spaced-family-font-does-not-display-characters-any>
Using par(family="monospace") does work:
par(mfrow=c(1,2))
par(family="mono")
plot(1)
par(family="monospace")
plot(1)
Also, when saving to pdf, it works fine:
pdf("plot.pdf"); par(family="mono"); plot(1); dev.off()
I have forced a refresh of the font cache:
fc-cache -r --verbose --really-force
And Courier is available:
> fc-list | grep Courier
/usr/share/fonts/X11/Type1/c0419bt_.pfb: Courier 10 Pitch:style=Regular
/usr/share/fonts/type1/texlive-fonts-recommended/pcrb8a.pfb:

/usr/share/fonts/X11/Type1/c0611bt_.pfb: Courier 10 Pitch:style=Bold Italic
/usr/share/fonts/type1/texlive-fonts-recommended/pcrr8a.pfb:

/usr/share/fonts/X11/Type1/c0582bt_.pfb: Courier 10 Pitch:style=Italic
/usr/share/fonts/X11/Type1/c0583bt_.pfb: Courier 10 Pitch:style=Bold
/usr/share/fonts/type1/texlive-fonts-recommended/pcrro8a.pfb:
Courier:style=Italic
/usr/share/fonts/type1/texlive-fonts-recommended/pcrbo8a.pfb:

Any other ideas how to fix this?
Best,
Wolfgang
