User $user has no calendar subscription with the URI $uri

Error message

User $user has no calendar subscription with the URI $uri

What it means

Thrown by the occ dav:delete-subscription command when CalDavBackend::getSubscriptionByUri('principals/users/<uid>', $uri) returns null, i.e. no calendar subscription row matches that principal and URI pair. It is an InvalidArgumentException raised before anything is deleted, so the command aborts with no side effects. Subscriptions are cached remote calendars created with dav:create-subscription, distinct from real calendars.

Solutions

1. Run `occ dav:list-subscriptions <uid>` and copy the exact URI from the first column
2. Verify the user id exists with `occ user:list` or `occ user:info <uid>`
3. If the target is a real calendar rather than a subscription, use `occ dav:delete-calendar <uid> <uri>` instead
4. If the subscription is not listed at all, it is already gone and there is nothing to delete

Example fix

# before
occ dav:delete-subscription alice personal
# InvalidArgumentException: User alice has no calendar subscription with the URI personal

# after
occ dav:list-subscriptions alice
# URI:                # DISPLAYNAME: ...
# personal-friends    Friends calendar
occ dav:delete-subscription alice personal-friends

#!/usr/bin/env bash
# confirm the subscription exists before deleting
uid="$1"; uri="$2"
if ! occ dav:list-subscriptions "$uid" | awk 'NR>1 {print $1}' | grep -Fxq "$uri"; then
  echo "No subscription '$uri' for $uid — aborting" >&2
  exit 1
fi
occ dav:delete-subscription "$uid" "$uri"

When it happens

Trigger: Running `occ dav:delete-subscription <uid> <uri>` where the URI is misspelled, belongs to a different user, was already deleted, or is actually a real calendar URI (not a subscription). The lookup is scoped to principals/users/<uid>, so a URI that exists for another user still yields null.

Common situations: Admin copies the display name from the calendar UI instead of the URI; the subscription was already removed in the UI; wrong user id (typo, deleted account); confusing dav:delete-calendar with dav:delete-subscription.
