Error summary:

- Exact error message and exit code:
  - "ERROR: failed to build: failed to solve: process \"/bin/sh -c make check VERBOSE=1\" did not complete successfully: exit code: 2"

- Failing command/step:
  - Step [8/9] RUN make check VERBOSE=1

- Missing packages or files mentioned:
  - Test files not found (causing skips):
    - t_server_null.sh: "./t_server_null.sh: cannot find './t_server_null.rc'. SKIPPING TEST."
    - t_client.sh: "./t_client.sh: cannot find 't_client.rc' in build dir ('..') or source directory ('.'). SKIPPING TEST."
  - Runtime tooling missing for tests:
    - "ip" command not found (t_net.sh reports "ip: command not found"), leading to failure in System Tests: "can't create interface ovpn-dummy0".
  - Base image/toolchain info:
    - FROM ubuntu jammy-20260210.1 (as shown by the build log).

- Version mismatch info:
  - Apt install shows: "3 upgraded, 88 newly installed, 0 to remove and 8 not upgraded."
  - Toolchain mix: multiple GCC toolchain packages are upgraded/installed (gcc-12-base, libstdc++6, etc.) alongside existing gcc-11 components (e.g., gcc-11-base, gcc-11, g++-11). This indicates a mixed GCC environment (gcc-11 and gcc-12 present/upgraded) during the build.
  - These version shifts occur during the RUN apt-get install -y ... step in the Ubuntu base image.

Context: OpenVPN unit tests largely pass, but System Tests fail due to missing iproute2/ip and missing rc test files, resulting in the overall docker build failing at make check with exit code 2.

Summary of Docker build error

- Exact error message and exit code
  - ERROR: process "/bin/sh -c make check VERBOSE=1" did not complete successfully: exit code: 2

- Failing command/step
  - [ 9/10] RUN make check VERBOSE=1

- Missing packages or files mentioned
  - t_client.sh reports missing test RC file:
    - "./t_client.sh: cannot find 't_client.rc' in build dir ('..')"
  - t_server_null test rc handling errors (RC misparsed):
    - "./t_server_null.sh: 1: ./t_server_null.rc: -E: not found"
    - "./t_server_null_server.sh: 1: ./t_server_null.rc: ./t_server_null_client.sh: 1: ./t_server_null.rc: -E: not found"
  - System test environment issues surfaced:
    - Cannot open TUN/TAP device: "Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)"
    - "Cannot find device 'ovpn-dummy0'"
  - Result: multiple OpenVPN system tests fail to start, with 0/4 servers up in several runs

- Version/compatibility information (mismatches)
  - Base image: ubuntu jammy (jammy-20260210.1)
  - OpenVPN and related libs reported:
    - OpenVPN 2.8_git
    - OpenSSL library: OpenSSL 3.0.2
    - LZO: 2.10
  - Kernel/driver capability note:
    - "Note: Kernel support for ovpn-dco missing, disabling data channel offload."
  - Implication: missing /dev/net/tun capability in the container (kernel/module support) and RC parsing issues in test scripts contribute to test failures

- Additional context
  - Unit tests (17/17) passed, but system tests failed (2 FAIL, 2 PASS, 1 SKIP in system tests; overall system tests 5 total, 2 PASS, 2 FAIL, 1 SKIP)
  - The build progressed through many apt installs and build steps before the failing make check step, but the failures stem from test harness/ENV issues and RC/script problems rather than compilation.
