One of my RPis has a problem with
root@sent121:~# python3 Segmentation fault
When debugging a
print('hello') script I get

There is nothing special about this particular RPi - there are ~20 like him managed the same way and it is the only one and they work fine. But magical things happen with computers and I get it that the binary is somehow corrupted.
I tried to reinstall it but ...

I am not sure how to interpret it - either the install depends on
python3 or an upstream library is corrupted (impacting some binaries). This is not a generalized issue, it touches only some of the libraries so it may be a
root@sent121:~# lsb_release -a Segmentation fault root@sent121:~# uname -a Linux sent121 4.9.59-v7+ #1047 SMP Sun Oct 29 12:19:23 GMT 2017 armv7l GNU/Linux root@sent121:~# curl http://google.com > /dev/null % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 266 100 266 0 0 348 0 --:--:-- --:--:-- --:--:-- 348
deb binaries for
python3 I could install with
dpkg which seems to be ok?
root@sent121:~# dpkg --version Debian 'dpkg' package management program version 1.18.24 (armhf).
This RPi is far away from me so I would prefer to solve the issue remotely rather than reinstall the card (which I will arrange for is needed)
