Install Doctor

When you hit “command not found”, a missing shared library, or a missing compile-time header, you no longer need to guess the package name. Paste the error below — the tool identifies what’s missing and gives you the install command for your distribution.

Supported Error Types

Section titled “Supported Error Types”
ExampleDetected as
-bash: tree: command not foundMissing command → package that provides it
zsh: command not found: nodeSame, zsh format
error while loading shared libraries: libssl.so.3Missing shared library
fatal error: openssl/ssl.h: No such file or directoryMissing compile-time header (auto-expanded to the /usr/include/ path for lookup; needs a *-devel package)
/usr/bin/ld: cannot find -lpngMissing link-time library (auto-converted to a libpng.so query)
Any absolute path (e.g. /usr/sbin/nginx)File path reverse lookup

You can also type a command name (e.g. htop) or a file path (e.g. /usr/sbin/nginx) directly.

How It Works

Section titled “How It Works”
  1. The error text is parsed locally in your browser to extract the missing command, library, or header path — your input is never sent to this site’s server
  2. The tool queries the public pkgseek.com API to find which official-repository package ships that file
  3. You get the matching dnf install command for your distribution, ready to copy
