Spellchecker disappears when upgrading 6.3 on debian

Hello everyone,
We have installed Onlyoffice Docs Community Edition 6.3 on a machine working with Debian 10, in order to use it with owncloud. We now want to upgrade it in 6.4 or 7.0 but each time we try to do it, spellchecker disappears. We tried to re-install our machine from scratch and re-experienced the same problem : spellchecker is not installed. Does anyone encounters the same problem, what is the solution ?
Thanks for any help and best regards,

Hello,

Does spell checking stop working in the editors after updating, or do you mean that the spellchecker component no longer gets installed?

If it’s the latter, there is a simple explanation: starting from 6.3, the spellchecker no longer exists as as a separate service, which is mentioned in the changelog: https://github.com/ONLYOFFICE/DocumentServer/blob/master/CHANGELOG.md#630

However, the functionality itself should still work.
