All Errors

The 'Missing resource instance key' error occurs when you try to access attributes of a resource that has for_each set without specifying which instance to access. Fix it by using specific instance keys like aws_instance.example[each.key].id or using a for expression in outputs.

This error occurs when Terraform tries to reference a module that hasn't been declared in the current configuration scope. Learn how to properly declare modules and pass values between them.

Terraform state lock errors occur when Terraform cannot acquire an exclusive lock on your state file, usually due to concurrent operations, stale locks, or hung processes. This error prevents infrastructure changes and requires identifying and releasing the conflicting lock.

This error occurs when Terraform cannot acquire a lock on your Azure Blob Storage state file because another process or operation already holds the lock. It typically happens when multiple pipelines run concurrently or when a previous operation terminated unexpectedly.

The Terraform AWS provider plugin crashes during plan or apply operations. This is typically caused by version-specific bugs, memory constraints, or problematic resource configurations. Most cases are resolved by upgrading to a patched provider version or downgrading to a stable release.

The InvalidParameterCombination error occurs when your Terraform aws_db_instance configuration contains incompatible parameter values. This error is caused by mismatches between the database engine, instance class, storage settings, or other parameters. Resolving it requires identifying which parameters conflict and updating your configuration.

This error occurs when apt cannot establish a connection to a configured proxy server. Common causes include incorrect proxy configuration, unreachable proxy server, wrong credentials, or firewall blocking.

The "Cannot set to hold" error occurs when attempting to hold an uninstalled package using apt-mark. This is intentional behavior by dpkg—held status only works on installed packages. Uninstalled packages can be locked from installation using APT preferences instead.

The dpkg package manager encountered a corrupted .list file in /var/lib/dpkg/info/ that contains an empty filename. This prevents apt from functioning and requires manual repair of the corrupted package metadata.

The "no installation candidate" error for i386 packages occurs when apt cannot find a suitable version of a 32-bit package due to multiarch not being enabled, missing repositories, or version conflicts. Enable i386 support and update your package cache to resolve this.

The "invalid for APT::Default-Release" error occurs when the release name specified in your APT configuration doesn't match any release in your sources.list. This prevents apt from finding the specified distribution, causing package installation to fail.

The "dpkg: error: unable to create new file: Permission denied" error occurs when your user account lacks sufficient permissions to modify package management directories. This is almost always resolved by running the command with sudo privileges.

The dpkg error code (2) typically occurs when the package manager encounters file system or permission issues, corrupt package lists, or incomplete installations. This can usually be fixed by reconfiguring dpkg, fixing broken dependencies, or removing lock files.

The "dpkg-divert: error: rename involves overwriting" error occurs when dpkg-divert tries to rename a file during package operations but finds a different file in the target location. This typically happens due to package conflicts, leftover files from failed installations, or incorrect diversion configurations.

The dpkg post-removal script error occurs when a package's cleanup script fails during uninstallation or upgrade. This typically affects kernel images, system libraries, or packages with custom removal logic. Fix it by reconfiguring dpkg, repairing broken dependencies, or manually editing the problematic script.

The "Sub-process /usr/bin/dpkg returned an error code (1)" error occurs when the Debian package manager fails during kernel installation, typically due to corrupted package database, interrupted installation, or insufficient disk space. This can be fixed by reconfiguring dpkg, fixing broken dependencies, or freeing disk space.

This error occurs when dpkg cannot complete package configuration due to unmet dependencies. Triggers are post-installation actions that fail when required packages are missing or unconfigured. It typically happens after interrupted installations or when installing packages with complex dependency chains.

This error occurs when dpkg's package database becomes corrupted or damaged. It prevents package installation, updates, and removal until resolved. Most fixes involve clearing locks, reconfiguring dpkg, or restoring backup database files.

The dpkg error processing package message occurs when the package manager encounters a problem during installation, often due to broken dependencies, corrupted package metadata, or interrupted installations. Fix it by reconfiguring dpkg, fixing broken packages, or clearing corrupted metadata.

This error occurs when apt cannot establish a connection to a package repository server. It usually stems from network issues, DNS problems, or repository server unavailability and can be resolved by checking connectivity and updating repository configurations.
