Got error when building image to exec file

[ilu123]

I tried to use it to build gitlab docker image into a executable file:

./dockerc --image docker-daemon:gitlab/gitlab-ce:13.8.8-ce.0 --output gitlab

and got error message like this:

mksquashfs: dl-call-libc-early-init.c:37: _dl_call_libc_early_init: Assertion `sym != NULL' failed.

How did you build the gitlab image? Is there a different image that you have succeeded in building (so the bug is gitlab specific)?

I see that glibc versions are not the same. It could be related.

Regarding this issue it happens on a Ubuntu 20 machine:

@MathieuB1 what arguments did you specify to dockerc?

[MathieuB1]

./dockerc --image docker-daemon:$APP_NAME:$APP_VERSION --output bin/xxx

But the same command works in my local desktop Ubuntu 20

[MathieuB1]

Finally I fixed it by upgrading my ubuntu20 on the server. There was outdated packages.
