Restore from backup in new VM with official qcow image does not accept backup file

[pipboy20k]

The problem

Hi all!

I have set up a new VM via libvirt and virt-install according to https://www.home-assistant.io/installation/linux/

The VM comes up and I can start with "Create My Smart Home, connect to mosquitto and zigbee2mqtt (running in containers outside of the VM), everything seems fine.

If I instead choose to "Restore From Backup" and choose a backup I made I get a popup "Unsupported file format: Please choose a Home Assistant backup file (.tar).

I have tried different backups:

• a backup from my "old" instance
• one I created after running the VM anew like described above and configuring some things

both are full backups that I created via Firefox in the WebUI from a Windows machine.

Expected behaviour: the backup tar file is accepted

Not sure if this is connected to https://github.com/home-assistant/core/issues/108131 or https://github.com/home-assistant/core/issues/92282

What version of Home Assistant Core has the issue?

core-2024.3.0

Maybe related to https://github.com/home-assistant/frontend/issues/7258 :thinking:

Can you try download and upload using Chrome?

Can you try download and upload using Chrome?

wow, perfect guess, with chrome the file is accepted (goes for files downloaded by either FF or Chrome).

Maybe related to home-assistant/frontend#7258 🤔

looking at that issue I see the "tried another browser" line. I guess I should have tried posting this under frontend and would have been served my workaround automatically^^

Whether you still consider this an issue or not is up to you. Me personally I'm fine with using Chrome. Thanks agners!
