Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:

The following packages have unmet dependencies:
builddeps:csound : Depends: ttf-dejavu but it is not installable
E: Unable to correct problems, you have held broken packages.
What can be done?
Thanks for Your help,

this is a strange error message but it means you have to install the "dejavu" font (ttf = true type font).

i guess you can install it with a tool in ubuntu; perhaps it is also on fonts.google.com.

Dear Joachim,
thanks for Your reply.
I think I already have the font installed, at least if I can trust the attached screenshot from font-manager.

perhaps you can look if your installation is ttf or otf (open type font).

otherwise i would just go on with the installation of csound. you can install packages which might miss later if they are required.

Ok, I will try and proceed with the installation!

Ok, I’ve got new error messages:
– Could NOT find CURL (missing: CURL_LIBRARY CURL_INCLUDE_DIR)
– Not using CURL for urls - not found.

– Could NOT find BISON (missing: BISON_EXECUTABLE)
CMake Error at CMakeLists.txt:637 (message):
Csound requires the flex executable

I’ve no idea what they could mean.

Ok, I understood: I had to install bison and flex, whatever they are, but it seems, that I’ve installed csound successfully.

Bison is the system used to parse the csound language; flex is a tokeniser used with bison. To understand the joke search for yacc.
