Update to 0.116.2 fails

I am running 0.116.1 as a VM. When I try to update to 0.116.2, I get an error box saying “Update failed, Unknown error, see logs”. As far as I can tell, there is nothing in the logs.

I had started out with 0.114 and updated several times without issues. How to figure out what is going on with this update?

Thanks,
Arun

Issue resolved. For some reason, HA does not like a Firefox add-on called Dark Reader. I have noticed that when this add-on is enabled (even if it is disabled for HA pages), it causes a major slowdown in loading HA screens like Automations, Scripts and so on. Remembering that, I disabled the add-on and then upgrade worked fine.
