solo2 update not working on Ubuntu

[maddler]

Hello, I've just tried to update firmware on one of the SoloKey2 I just received.
I get prompted to tap to confirm, the led on the key goes off bit then I get a tiemout error:

❯ solo2 update
Downloading latest release from https://github.com/solokeys/solo2/
Fetched firmware version 1:20200101.9 (1.0.9)
Tap button on key to confirm, or replug to abort...
Error: User prompt to confirm maintenance timed out!
❯ solo2 -V
solo2 0.2.0

I installed solo2 with cargo install.
I was able to update the SoloKey2 on Mac with no issues.

Solo 2 F4090C8FDD7CBA5E93409795223151E7 (CTAP+PCSC, firmware 1:20200101.9)

The solo2 is already on the latest version?

Pretty sad there was no acknowledgement on this bug since., nor any update on the tools.

@maddler : Have your tried to add 70-solo2.rules in udev ?

The one from solo2-cli have an extra entry needed for firmware update in user mode.

Hello Alex,
the udev-rule work:

The same happens on Fedora 36.

Fedora 36

• add 70-solo2.rules to /etc/udev/rules.d/70-solo2.rules
