Hi, I have simulated the eglot-tests from EMBA in my local environment. Instead of using Debian bullseye (stable), I have taken Debian sid (unstable). Additionally, I have installed the respective Debian sid packages: --8<---------------cut here---------------start------------->8--- # apt list clangd python3-pylsp python3-autopep8 python3-yapf Listing... Done clangd/now 1:14.0-55.6 amd64 [installed,local] python3-autopep8/now 2.0.1-1 all [installed,local] python3-pylsp/now 1.7.1-1 all [installed,local] python3-yapf/now 0.32.0-1 all [installed,local] --8<---------------cut here---------------end--------------->8--- However, eglot-tests still fail for pylsp, see attached eglot-tests.log file. Best regards, Michael.
