Disable apps “bookmarks” or “files_external_gdrive” if they are in use before upgrading nextcloud. These apps ship an incompatible version of guzzle. You may identify other apps with incompatible guzzle by using following command: find /<path_to_nextcloud>/apps -iname "guzzle*"

[cyrg38]

The only app getting guzzle I have is "files_external_gdrive".

In fact, the fresh re-install produced an effect on upgrading database I think, so that switching again on old install I can get on to the promised 14 version : getting here back with GUI access.

This is SOLVED for me ! Thanks.
