Hi Michael,=

I built an Emacs version from the current master branch and tried it out: lsp-mode works well with a remote clangd now. Unfortunately there are some = other problems, which do not occur with Emacs 27.1 and which might be relat= ed to TRAMP:
- my remote compile setup does not work anymore. It seems that the argument= s to the invoked compile command are lost on the way to the remote machine<= br> - rgrep on a remote machine also does not work. It produces a list of files= it intends to search instead of the grep output
- I also encountered an error message from TRAMP once. Unfortunately I rest= arted Emacs afterwards, so I don't have the exact error message. It was= something about a recursive call detected and a sentinel was mentioned.
Best Regards,

Martin
