Bug#1005906: strace from rocker/r-base:4.1.2
Sorry, I got the base image wrong when experimenting with strace. Here's my updated Dockerfile. I've confirmed that this bug still happens when I *only* install libc6 (and dependencies):
--- begin Dockerfile ---
FROM rocker/r-base:4.1.2
COPY ./test_executable.sh /usr/local/bin
RUN test_executable.sh # works
RUN apt-get update && apt-get install -y strace
RUN test_executable.sh # works
RUN apt-get install -y libc6
RUN test_executable.sh # doesn't work
--- end Dockerfile ---
Working:
ii libc6:amd64 2.32-4 amd64 GNU C Library: Shared libraries
Not working:
ii libc6:amd64 2.33-5 amd64 GNU C Library: Shared libraries
When installing/upgrading libc6, apt also installs the following packages:
libc-bin libc-dev-bin libc-l10n libc6 libc6-dev locales
