Yubico-key not recognized in Ubuntu 20.04

[Seppo]

Hi!

I have used Passwordsafe successfully many years in various Ubuntu LTS
versions, and now in 20.04 it does not recognize my Yubico key.

Last success was in 18.04 with Passwordsafe V1.7.

I have tried in Ubuntu 20.04

- 1.8.02 (standard package offered from Canonical)

- 1.010 from Sourceforge

- 1.011 from Sourceforge

without success.

Yubico key button does not appear. Known bug?

Regards,

Seppo

• Does lsusb show the YubiKey device?
• Can you access it with the YubiKey Manager?

Hi Rony!

You responded quickly, but I was away on a COVID retreat on my summer cottage away from my linux laptop.

Answers to your questions:
-Yes, lshub shows yubikey
Bus 003 Device 002: ID 1050:0010 Yubico.com Yubikey (v1 or v2)

• Yubikey Manager installed it and it lists OPT as enabled a

• command ykman info gives:

  Device type: YubiKey Standard
  Serial number: 1618084
  Firmware version: 2.3.1
  Enabled USB interfaces: OTP

  Applications
  OTP Enabled
  FIDO U2F Not available

What next?

Hi,

I removed PWSAFE, rebooted laptop, reinstalled PWSAFE (1.8.02 BETA) from Ubuntu Software.

I started PWSAFE, installed Yubikey. No Yubikey button.

I now checked logs, and saw that PWSAFE had reported numerous lines like:

Negative content height -5 (allocation 1, extents 3x3) while allocating gadget (node button, owner GtkButton).

PWSAFE window can be extended only horisontally, cannot add the height of the window...

Don't know what to try next,

OK,

I found it!

I started to get a feeling, that after all it had nothing to do with the Yubikey.

I logged out, changed screenhandling from Wayland to X11, and PWSAFE window appeared normally. Earlier I had been doing some testing with different applications and their compatibility, and had forgot the position which I had toggled the session window management.

At least I have now way forward, and can upgrade the rest of my household linuxes to 20.04 without the mission critical application called Password Safe.

Thank you for this critical app!

Have a nice day!

Regards,
Seppo

I am not sure about Ubuntu, but I do know that on Linux Mint to use a YubiKey in general in your web browser I had to use the following link to get it working as it does not work by default... https://www.yubico.com/authentication-standards/fido-u2f/#toggle-id-9

once I did that, the standard/basic blue YubiKey works (NOTE: the standard YubiKey won't work on Password Safe) through web browsers to login to Google account etc.
