Same issue here, but with a few differences to the original report:

  • Raspberry Pi board version 4

  • PiKVM platform v2

  • KVMD version: pacman -Q | grep kvmd generates:
    kvmd 3.332-1
    kvmd-fan 0.30-1
    kvmd-oled 0.27-1
    kvmd-platform-v2-hdmiusb-rpi4 3.332-1
    kvmd-webterm 0.49-1

@4plb0mb commented on GitHub (May 13, 2024):

Same here, except for a couple things:

  • Hardware are 2x pikvm v4 plus

  • update command is pikvm-update (although I know that it's "just" a script that also uses pacman)

Both v4's pacman -Q | grep kvmd:
kvmd 3.333-1
kvmd-fan 0.30-1
kvmd-oled 0.27-1
kvmd-platform-v4plus-hdmi-rpi4 3.333-1
kvmd-webterm 0.50-1

pacman -Q | grep ustreamer
ustreamer 6.11-1

and finally uname -a
Linux pikvm-004 6.6.21-4-rpi #1 SMP Wed Mar 13 20:36:42 UTC 2024 armv7l GNU/Linux

Having the same issue. Also, noticed for little over a week no updates from Arch so made me wonder what is up.

This happens when Python is updated in the distribution. We have a pinned version, so that nothing breaks because of the update. Everything worked as it should.

Updated now.

@mdevaev

Thanks for the quick follow-up, after your comment I see now that the error changed, none of the original dependency conflicts are there, but there is one new one:

error: failed to prepare transaction (could not satisfy dependencies)
:: installing python (3.12.3-1) breaks dependency 'python<3.12' required by python-ajsonrpc

Run pacman -R python-ajsonrpc and perform update again.

pikvm-update gives this error:

:: installing python (3.12.3-1) breaks dependency 'python<3.11' required by python-ajsonrpc
++ on_error
++ set +x

  An unexpected error occurred during the update.

==============================================================

and the solution above gives this error:

[root@pikvm kvmd-webterm]# pacman -R python-ajsonrpc
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: removing python-ajsonrpc breaks dependency 'python-ajsonrpc' required by platformio

@tim-lux commented on GitHub (May 25, 2024):

I also ran into this issue:
removing python-ajsonrpc breaks dependency 'python-ajsonrpc' required by platformio
(following a chain of dependencies, so removing it did not)

As some suggested on the discord, reinstalling worked for me (rpi 4, pikvm 3): pacman -S python-ajsonrpc
