Thanks for reporting this!

Is this reproducible on a clean RasPi OS install? It looks like there may be something wrong with your package manager on that particular system.

E: Unable to correct problems, you have held broken packages.

It's also possible that some of the apt packages changed and the dependencies need to be updated, but if you could try it on a clean system, that would be helpful.

Hi,

It was a fresh install, brand new from latest image - installed about 30 mins before I attempted to install tinypilot. Admittingly, it's not a completely untainted installation, as I normally bring my system up-to-date with my standard user configuration (using ansible) before I do anything else.

I did install tinypilot on the same machine, last week without issue, from again a fresh base installation (I wiped the card this morning to try something out, so rebuilding things again).

I can attempt again with another fresh install, before I do my user ansible setup.

Hi,

Fresh install, no issues detected. I suppose something that I install prior gets in the way. Happy to close this issue as not a fault of tinypilot. :-)

Thanks for letting me know!
