CRI-O fails to detect link mode of binary on non english language OS #5165
Description
Description
I'm using CRI-O static in a ubuntu server with spanish locale (LANG=es_ES.UTF-8) and logs shows the following error every few seconds:

Seems that code is using text output from command ldd and expect an exact result, and it is not the case with non-English languages. The output of ldd /usr/local/bin/crio in my system is
$ ldd /usr/local/bin/crio
no es un ejecutable dinámico
As a workaround , if I add
Environment=LANG=C
in systemd crio.service the error disappears.
Additional information you deem important (e.g. issue happens only occasionally):
