All Errors

This message appears when Git detects worktree administrative data pointing to directories that no longer exist. Learn how to prune stale worktrees or repair broken references.

pip searched PyPI and couldn't find a version of the package that matches your version constraints and Python version.

This Docker build error occurs when you reference an ARG variable that hasn't been declared, or when the ARG declaration loses scope due to multi-stage builds. Fix it by declaring ARG before use and redeclaring after each FROM instruction.

A Flannel backend error occurs when the pod networking plugin fails to set up or maintain the overlay network. Flannel provides cross-node pod communication via VXLAN, UDP, or host-gw backends. Backend failures prevent pods from communicating across nodes, causing total network isolation.

This error occurs when npm can't verify the cryptographic signature of a package. Usually caused by package publishing issues, registry problems, or tampering detection.

The 'gpg failed to sign the data' error with 'No secret key' occurs when Git tries to sign a commit but GPG cannot find the private key configured in your Git settings. This typically happens when your signing key ID is misconfigured, the key was never imported, or GPG is looking in the wrong keyring.

This Git error occurs when you try to push commits but the remote branch has new commits you don't have locally. Fix it by pulling remote changes first with 'git pull' or 'git pull --rebase', then push again. Force pushing should only be used when you intentionally want to overwrite remote history.

This error occurs when Git cannot find the specified commit reference, usually because the repository has fewer commits than requested or you're working with a shallow clone that lacks sufficient history.

The 'ssh: connect to host github.com port 22: No route to host' error means your system cannot find a network path to reach GitHub's SSH server. This typically indicates a network-level issue such as firewall blocking, incorrect routing, or the SSH port being filtered by your ISP or network administrator.

Workload Identity fails when service account bindings are incomplete, KSA annotations are missing, or IAM permissions are misconfigured. Pods cannot access Google Cloud APIs.

This error occurs when Git detects uncommitted changes in your working directory that conflict with incoming changes from a merge. You need to either commit, stash, or discard your local changes before Git can proceed with the merge.

This error occurs when the Docker daemon receives a malformed or invalid request from the client. Common causes include API version mismatches, invalid container/image names, and proxy configuration issues.

This Git error occurs when you run `git reset` and there are untracked files in your working directory that would be overwritten or removed by files from the target commit. Git prevents the reset to protect your untracked work from being silently deleted.

The 'fatal: Not a valid object name' error occurs when Git cannot find the branch, tag, or commit you're referencing. This typically happens in freshly initialized repositories before the first commit, or when referencing a branch that doesn't exist yet.

This Git error occurs when a merge operation was started but not completed. The MERGE_HEAD file still exists in your .git directory, indicating Git is waiting for you to either finish the merge by committing or abort it entirely.

This error occurs during a Git merge or rebase when a file was renamed in one branch but deleted in another. Git cannot automatically resolve this conflict because it involves a structural change to the file tree, not just content differences. You must manually decide whether to keep the renamed file or accept the deletion.

Pod scheduling fails when requiredDuringSchedulingIgnoredDuringExecution affinity rules cannot be satisfied. No nodes match the required labels, node resources, or topology constraints.

Headless Service (clusterIP: None) cannot resolve because no pods match the Service selector. DNS returns no A records, stateful applications cannot discover members.

Invalid label values violate Kubernetes naming conventions, preventing resource creation or updates. Labels must follow specific rules for characters, length, and format.

Leader election failures prevent controllers from achieving high availability. When multiple replicas of a controller (operator, webhook, scheduler) cannot elect a leader, none may process events, disrupting cluster operations.
