User <$userOrigin> has no calendar named <$name>. You can ru

Error message

User <$userOrigin> has no calendar named <$name>. You can run occ dav:list-calendars to list calendars URIs for this user.

What it means

Thrown by occ dav:move-calendar when CalDavBackend::getCalendarByUri('principals/users/<sourceuid>', $name) returns null: the source user has no calendar with that URI. The name argument must be the calendar URI (the dav:list-calendars output), not the display name. Nothing is moved.

Solutions

1. Run `occ dav:list-calendars <sourceuid>` and use the exact URI column value
2. Quote the name in the shell to avoid globbing/whitespace issues
3. If the calendar is a subscription, note that move-calendar handles calendars only — move it via create/delete subscription

Example fix

# before
occ dav:move-calendar alice bob Work
# User <alice> has no calendar named <Work>. You can run occ dav:list-calendars ...

# after
occ dav:list-calendars alice
# URI: ...
# work-1
occ dav:move-calendar alice bob work-1

#!/usr/bin/env bash
src="$1"; dst="$2"; name="$3"
if ! occ dav:list-calendars "$src" | awk 'NR>1 {print $1}' | grep -Fxq "$name"; then
  echo "Calendar '$name' not found for $src" >&2; exit 1
fi
occ dav:move-calendar "$src" "$dst" "$name"

When it happens

Trigger: `occ dav:move-calendar <src> <dst> <name>` where name is the display name instead of the URI, has a typo, or the calendar belongs to a different user. Birthday calendars and subscriptions are not returned by getCalendarByUri for this path either.

Common situations: Admin copies 'Work' (display name) while the URI is 'work-1'; calendar already moved in a previous run; trailing whitespace or URL-encoded characters in the URI.
