Read the first 7 Software Package Management flashcards as text
What happens when you run `apt-get install -f` (or `--fix-broken`)?
Answer: Resolves and fixes broken package dependencies automatically
`apt-get install -f` attempts to correct broken dependencies by installing missing packages or removing conflicting ones.
Which `rpm` command rebuilds the RPM database after it becomes corrupted?
Answer: rpm --rebuilddb
`rpm --rebuilddb` rebuilds the RPM database from the installed package headers, fixing corruption issues.
In a YUM/DNF .repo file, what does the `enabled=0` directive do?
Answer: Disables the repository so it is not used by default
Setting `enabled=0` prevents DNF/YUM from querying this repository unless explicitly enabled with `--enablerepo`.
Which command shows which installed RPM packages have files that have been modified since installation?
Answer: rpm -Va
`rpm -Va` verifies all installed packages, reporting files whose attributes differ from the original package metadata.
What is the role of `/etc/apt/preferences` or `/etc/apt/preferences.d/` on Debian systems?
Answer: Defines package pinning rules that control which version APT installs
APT pinning in /etc/apt/preferences allows administrators to specify which package versions or repositories take priority.
What does the `dnf provides /usr/bin/python3` command do?
Answer: Shows which package provides the file /usr/bin/python3
`dnf provides` performs a reverse lookup to find which package supplies a specific file or capability.
When compiling software from source using the traditional method, which sequence is correct?
Answer: ./configure && make && make install
The standard build sequence is: configure (checks dependencies and sets up build), make (compiles), then make install (copies binaries).
