Now I uninstalled the texlive version of ConTeXt and did a total new install of the standalone version. That did not help at all. There's something wrong happening within the mtxrun.

I added a new "compiler" to TeXworks that only executes the command printenv and it lists the following environment settings:

TEXROOT=/usr/local/context/tex

PATH=/usr/local/context/texmf-linux-64:/usr/local/context/bin:/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/context/texmf-linux-64/bin

OSFONTDIR=/usr/local/share/fonts;/usr/share/fonts;/home/thomas/.local/share/fonts

They look pretty correct to me. But still mtxrun complains:

----------------------------------------------

... resolvers | resolving | warning: no lua configuration files found

resolvers | resolving | no texmf paths are defined (using TEXMF)

resolvers | resolving |

mtxrun | the resolver databases are not present or outdated

...

resolvers | resolving | warning: no lua configuration files found

resolvers | resolving | no texmf paths are defined (using TEXMF)

...

mtxrun | unknown script 'context.lua' or 'mtx-context.lua'

----------------------------------------------

To prevent misunderstandings: This is not the solution, the problem remains that the newly installed standalone mtxrun doesn't find certain configuration files and complains about an outdated something or other, when started from within TeXworks, while everything works fine from the command line.

Can you check the paths in the fourth tab (= Typesetting) of Preferences/Settings? It is possible that you have more than one version of ConTeXt installed and that you see different paths in the Terminal than in the GUI. Mojca

Yes I have two versions of ConTeXt. I have TeXlive from the Ubuntu repository and now the newer version as standalone. I added the paths to the new version at the top of that list in TeXwoks' preferences. And it does find and run the new version of mtxrun.
