Anybody an idea, why? I did delete hugo and jsut uploaded the latest version again and unpacked it onto the server. Even a try in a different folder /NEWBIN did not work. Same results as in /bin
It’s not quite clear to me WHERE EXACTLY your hugo binary is located. You should use it via absolute path from root, like /path/to/where/you/installed/hugo instead of ./path/to/hugo.
Also make sure that the file is executable with chmod +x hugo.
I did upload it again using a different basic folder (NEWHUGO), and also ./hugo new site NAME as I read somewhere, that all-inkl.com needs the ./ before hugo. It worked. Strange.
I will therefore mark this as solution and close the thread. Thanks to all for your help!
