 +===== Connection closed by remote host =====
 +
 +On 22 CPU machine, when Buildroot is in parallel download mode (''BR2_PER_PACKAGE_DIRECTORIES=y''):
 +
 +<code>
 +kex_exchange_identification: Connection closed by remote host
 +Connection closed by 192.168.64.240 port 22
 +</code>
 +
 +In Gitlab server logs:
 +<code>
 +gitlab sshd[1800758]: error: beginning MaxStartups throttling
 +gitlab sshd[1800758]: drop connection #10 from [192.168.65.128]:37112 on [192.168.64.240]:22 past MaxStartups
 +</code>
 +
 +Solution: [[https://docs.gitlab.com/topics/git/troubleshooting_git/#ssh_exchange_identification-error|ssh_exchange_identification]]

 +
 +===== remote: You are not allowed to download code from this project. =====
 +
 +<code>
 +Cloning into '/builds/group/project/buildroot/src/maginc-submodule'...
 +remote: You are not allowed to download code from this project.
 +fatal: unable to access 'https://gitlab.example.com/groups/project/magic-submodule.git': The requested URL returned error: 403
 +fatal: clone of 'https://gitlab-ci-token:[MASKED]@gitlab.example.com/groups/project/magic-submodule.git' into submodule path '/builds/group/project/buildroot/src/maginc-submodule' failed
 +</code>
 +
 +Reason:
 +[[https://docs.gitlab.com/ee/update/deprecations.html#default-cicd-job-token-ci_job_token-scope-changed|Default CI/CD job token (CI_JOB_TOKEN) scope changed]]

 +[[https://gitlab.grinndev.ovh/help/ci/jobs/ci_job_token#allow-access-to-your-project-with-a-job-token|Allow access to your project with a job token]]
 +
 +Solution:
 +  * Go to ''Submodule to be cloned'' in Gitlab UI
 +  * Settings --> CI/CD --> Token Access 
 +
 +===== fatal: No names found, cannot describe anything =====
 +
 +<code>fatal: No names found, cannot describe anything.</code>
 +
 +When ''git describe --tags'' is used to detect version name but repository doesn't contain tags.
 +
 +Possible reasons of failure:
 +  * shallow clone, to unshallow run ''sudo git fetch --unshallow''
 +  * gitlab ???
 +
 +
 +===== cannot run ssh =====
 +<code>
 +Synchronizing submodule url for 'xxx'
 +Cloning into 'xxx'...
 +error: cannot run ssh: No such file or directory
 +fatal: unable to fork
 +fatal: clone of 'git@gitlab.xxx:xxx/xxx.git' into submodule path 'xxx' failed
 +</code>
 +
 +Looks like SSH client is not installed in Job image (install ''openssh-clients'').
 +
 +**Reason:** During clone operation Gitlab Runner is using small helper (around 66MB) image where ssh client is not installed:
 +<code bash>
 +docker run --rm -it registry.gitlab.com/gitlab-org/gitlab-runner/gitlab-runner-helper:alpine-latest-x86_64-000bc602 ssh
 +</code>
 +
 +It is possible to chose flavour of helper image: [[https://docs.gitlab.com/runner/configuration/advanced-configuration.html#helper-image|helper-image]]
 +
 +Images source: [[https://gitlab.com/gitlab-org/gitlab-runner/-/tree/main/dockerfiles/runner-helper|runner-helper]]
 +
 +Ubuntu helper flavour contains ssh client:
 +<code bash>
 +docker run --rm -it gitlab/gitlab-runner-helper:ubuntu-x86_64-bleeding ssh
 +docker run --rm -it gitlab/gitlab-runner-helper:ubuntu-x86_64-v15.11.1 ssh
 +</code>
 +
 +
 +**Solution**: use Ubuntu based helper image:
 +<file toml config.toml>
 +  [runners.docker]
 +    helper_image = "gitlab/gitlab-runner-helper:ubuntu-x86_64-v16.0.2"
 +    helper_image_flavor = "ubuntu"
 +</file>
 +
 +**Workaround 1:** use relative submodules as described in [[https://docs.gitlab.com/ee/ci/git_submodules.html#using-relative-urls|Using relative URLs]]. Gitlab runner will use https to clone submodules.
 +
 +**Workaround 2:** [[https://docs.gitlab.com/ee/ci/runners/configure_runners.html#rewrite-submodule-urls-to-https|Rewrite submodule URLs to HTTPS]]
