Upgraded and now get 404 not found

Steve_Winnard · August 27, 2018, 6:57am

Having been notified that there was an upgrade to HA, on several occasions but never having been able to upgrade due to various errors, I finally decided to get the upgrade done once and for all.

I managed this by doing a deinstall and then an install.

Once this had completed I was able to get the ui running, at least in a terminal window, but in my browser I get “404 not found”.

Here’s the log which seems to show a multitude of errors, and I’m not sure which are fatal and which can be ignored for now:

On the off-chance it was something in my config, I emptied and restarted. I now get this when I try staring the ui, then nothing

If you have an empty config file, that is probably the correct output. I think the way to proceed is to delete all the config files so that HA will re-create the default configuration when it starts.

You can then add your old configuration back one section at a time from your backup (which I hope you took), and fix the things that are now broken.

You need clean your config/deps folder. There were some outdated aiohttp lib blocked frontend loading.

I ended up rebuilding the machine, then upgrading to Ubuntu 18.04 to get the Python version I needed.

However, I have now gone full circle as when I try to install homeassistant, I get an error regarding not being able to import main from pip or something like that. This was the error I was getting right back at the start when I tried to perform the homeassistant upgrade.
sigh

Try to clean your config/.local folder if it exists. On my raspberry there were also installed some python packages in this folder which led to compatibility issues. Some modules could not be started during home assistant startup.
So I got the 404 not found error. After cleaning the config/.local folder and config/deps folder Home Assistant starts without an module error. I can open the Webgiu as normal.
