I opened an issue on Github but also wanted to post here if people were having this issue and looked here first.
Error during a fresh install on an Ubuntu LXC on Proxmox. I cloned the github repo and followed the install instructions. Cannot get any further in the installation process and the application will not get past the 502 NewsBlur is down screen
Steps taken
- Ran chmod 777 on db_mongo
- Changed image of image_proxy to latest instead of the one intended for ARM64
Error Block 1:
---> Starting NewsBlur development server...
