[Arch Linux] nitropy does not work any more

[klakomuc]

Hi,

I am afraid, nitropy does not work any more on Arch Linux (Linux archie 6.10.6-arch1-1 #1 SMP PREEMPT_DYNAMIC Mon, 19 Aug 2024 17:02:39 +0000 x86_64 GNU/Linux). Trying to execute nitropy nk3 status in GNOME Terminal results in:

/usr/lib/python3.12/site-packages/google/protobuf/internal/api_implementation.py:89: UserWarning: Selected implementation cpp is not available.

can not reproduce on Arch on current state, can you confirm you are having pynitrokey 0.4.50 installed ?

[klakomuc]

Due to the error message ImportError: libabsl_die_if_null.so.2401.0.0: cannot open shared object file: No such file or directory I assume that the error is related to python-protobuf (v27.3-2). Regardless of this, I have installed the latest version of python-pynitrokey (v0.4.50-1).

okok, v0.4.50 looks good, but the missing library is weird, so for me (on Arch) there is no: libabsl_die_if_null.so.2401.0.0 only /usr/lib/libabsl_die_if_null.so.2407.0.0 which originates in the abseil-cpp package in version 20240722.0-1.

Could you check your abseil-cpp version please and where this 2401 lib variant originates from?

[klakomuc]

I found out that libabsl_die_if_null.so.2401.0.0 is part of abseil-cpp 20240116.2-3, but abseil-cpp 20240722.0-1 is currently installed on my system. After downgrading to abseil-cpp 20240116.2-3 nitropy and nitrokeyapp works like a charm. A subsequent update to abseil-cpp 20240722.0-1 leads to exactly the error that I recently reported.

AFAIS this should be fixed by python-protobuf 27.2-2. Can you check if updating python-protobuf fixes the problem?

[klakomuc]

At the moment I have installed python-protobuf 27.3-2, and it does not work. I must have installed this version on 17.08.2024.

A downgrade to python-protobuf 27.2-2 is not possible without further ado due to an unfulfillable dependency.

However, there seems to be an update to python-protobuf 28.0-1 coming soon. When it is available, I will install it, test it and report back here.

[klakomuc]

An update to python-protobuf-28.0-2 could not solve the problem.

[robin-nitrokey]

Strange, I cannot reproduce this problem with:

$ pacman -Q python-pynitrokey
python-pynitrokey 0.4.50-1
$ pacman -Q python-protobuf
python-protobuf 28.0-2
$ pacman -Q abseil-cpp
abseil-cpp 20240722.0-1

If you try to run this line in Python directly, does it work?

$ python3
>>> from google.protobuf import descriptor
