FWIW my update to T5 here wrecked Nextcloud, among others, in such a manner that I cannot even reinstall it, even when deleting all the hosted data (which is more than a pain in itself)
But consider you lucky, you got a reaction : for me, I got absolutely no answer on this forum, one month after my post.
This is a concern, because I retain the impression that Turris is a thing for daring geeks ready to trash anything and restart from square one at any time, and not at all something one can rely on.
I am in a situation to recommend it to (only) a couple of users : at this time I just cannot risk they call me back next update with all their data disappeared.
Now if anyone here can react on my post from last month… Otherwise I’ll search around here for a procedure to completely factory reset everything -but even this, is not obvious to find.
