We store esphome in the nix store, which results in its file permissions being 0444. Esphome, when compiling a firmware image, will copy these files from the nix store to a working directory. When updating between versions it will notice these files changed and try to copy the new version over, which would break, because the user had no write permissions on the files. ❯ esphome compile 01e4ac.yml INFO Reading configuration 01e4ac.yml... INFO Detected timezone 'CET' with UTC offset 1 and daylight saving time from 27 March 02:00:00 to 30 October 03:00:00 INFO Generating C++ source... ERROR Error copying file /nix/store/lmzrgl1arqfd98jcss4rsmmy6dbffddn-esphome-1.19.2/lib/python3.8/site-packages/esphome/components/api/api_connection.cpp to 01e4ac/src/esphome/components/api/api_connection.cpp: [Errno 13] Permission denied: '01e4ac/src/esphome/components/api/api_connection.cpp' To fix this we modify chmod to 0644 just before esphome tries a copy operation, which will fix permissions on existing working directories just in time. |
