Nextcloud backup restore fails: add "/./" in path -- EDIT: If archivemount is installed

Hi all,

FIXED!

So, what’s happening:
In /usr/share/yunohost/helpers.d/filesystem:
In the function ynh_restore_file:

# Do a copy if it's just a mounting point
if mountpoint -q $YNH_BACKUP_DIR; then
    if [[ -d "${ARCHIVE_PATH}" ]]; then
        ARCHIVE_PATH="${ARCHIVE_PATH}/."
        mkdir -p "$DEST_PATH"
    fi
    cp -a "$ARCHIVE_PATH" "${DEST_PATH}"
# Do a move if YNH_BACKUP_DIR is already a copy
else
    mv "$ARCHIVE_PATH" "${DEST_PATH}"
fi

AHAH!

ARCHIVE_PATH="${ARCHIVE_PATH}/."

So that’s where it comes from!

I’m not proficient in bash, so I can only speculate there was a good reason for that to be there.
But since there’s a backup involving mv instead of a failing cp due to the “/./” in the path, I went for the simplest:

apt remove archivemount

Then I tried to restore again, and it worked! Actually it was much faster to restore successfully than to fail with the mount…

Of course, I’ve been in this for 3 days, and only now that I zeroed down on archivemount did I find…

https://forum.yunohost.org/t/problem-in-restoring-apps/3238/2

And that’s very very exactly the same issue…

I don’t know if archivemount is required or useful for anything else, but if not, could it be banned by adding a dependency conflict with yunohost?
