could not find in debug-info-directories

Error message

could not find %q in debug-info-directories

What it means

Returned by configureSetDebugInfoDirectories when the user runs `config debug-info-directories remove <dir>` and the given directory is not present in t.conf.DebugInfoDirectories. Delve only removes entries by exact string match from the configured list of directories searched for split DWARF debug info.

Solutions

1. Run `config debug-info-directories` with no argument to list current entries
2. Use the exact stored string, including trailing slash if present
3. Re-add the directory with `config debug-info-directories add <dir>` if you intended to add rather than remove

Example fix

// before
dlv> config debug-info-directories remove /usr/lib/debug/   # fails: stored as /usr/lib/debug
// after
dlv> config debug-info-directories                          # list
dlv> config debug-info-directories remove /usr/lib/debug    # exact match

dirs = t.conf.DebugInfoDirectories
if target_dir not in dirs:
    raise ValueError("%r not in debug-info-directories: %r" % (target_dir, dirs))

When it happens

Trigger: `config debug-info-directories remove /some/dir` where /some/dir was never added, was already removed, or differs textually (trailing slash, ~ unexpanded, relative path) from the stored entry.

Common situations: Cleaning up default debug-info directories (e.g. /usr/lib/debug) that were never added, typos, or shell paths with `~` that Delve stored unexpanded.
