Продолжительное время не обновлял свой пакет NextCloud. Он у меня оставался на 25 версии, а текущая ветка 27.
В уведомлениях висело сообщение что нужно выполнить команду (я использовал предустановленный образ ОС с Nexcloud) для обновления.
Выполнив заветную команду:
sudo bash /var/scripts/update.sh
Получал сообщение:
Please note that updates between multiple major versions are unsupported! Your situation is:
Current version: 25.0.2
Latest release: 27.1.2
It is best to keep your Nextcloud server upgraded regularly, and to install all point releases
and major releases, as skipping releases increases the risk of errors. Major releases are
16, 17, 18 and 19. Point releases are intermediate releases for each major release.
For example, 18.0.5 and 19.0.2 are point releases.

Please contact T&M Hansson IT AB to help you with upgrading between major versions.
