Package: python3-electrum
Version: 4.3.4+dfsg1-1
Severity: important

Dear Maintainer,

While it worked about a month ago, launching electrum with Ledger
hardware wallet attached produces this error:

```
No hardware device detected.
To trigger a rescan, press 'Next'.

On Linux, you might have to add a new permission to your udev rules.

(I've already installed python3-cbor and python3-serial to reduce
Jade-related errors)

python3-btchip is installed,

Also, HW wallet devices seems to be recognized:

```

```

Coudld this be due to transition to PEP 668? I don't recall if I needed
to pip-install any packages to make Ledger work.

Vincas,

Thank you for the information in your bug report and for your followup fix.

I do not personally own any hardware wallets, so I have not been able to test out hardware wallet support.

Based on what you have written, it would appear that the dependency you needed to have installed is not packaged in Debian.

https://pypi.org/project/ledger-bitcoin/

https://packages.debian.org/search?keywords=ledger

Also, it appears it might be specific to hardware manufactured by Ledger, although I admit that I do now know enough about the subject to be sure.

https://www.ledger.com/

In the future it would be ideal to package everything in Debian necessary to fully support hardware ledgers. However, as that is not likely to happen in the short term, I think it would be valuable to at least document what a user needs to add to get hardware wallets working in a README file installed with Electrum.

Would you be willing to send me a list of what you have done to get hardware wallets working for you and which hardware wallets are supported by these steps?

Thanks,

Soren

Yes it would be nice to have all these third party dependencies available. Not sure how feasible it is. Vendors could
contribute them by themselves if they though this was useful....

I only own Ledger, and it was enough to do `pip install ledger_bitcoin[hid]` as specified in
https://pypi.org/project/ledger-bitcoin/ to make it work again. I do not recall what I have additionally installed years
ago when I first started using Electrum.

The problem is that after some time in the future, I'll need to do the same thing again, and hope I remember what's
missing and not spam Debian bug tracker again :) .

I have added a proposed README file, which can be seen at:

https://salsa.debian.org/cryptocoin-team/electrum/-/merge_requests/16

Let me know if there is anything else I should add or if you think anything should be reworded.
