なぜインストールできなくなったのか教えてください。

raspberry Pi4 のSDカードを
OS:Raspbian GNU/Linux 10.3 (buster) raspberrypi 4.19.108
CANDY Pi Lite Service, version:7.0.3
の状態に戻し
sudo apt-get upgrade -y
で変化がないので
sudo /opt/candy-line/candy-pi-lite/uninstall.sh
curl -sL https://git.io/v7bXx | sudo bash
でインストールできました。
その後
sudo apt-get upgrade
sudo apt-get update
を繰り返して
OS:Raspbian GNU/Linux 10.6 (buster) raspberrypi 5.4.51
CANDY Pi Lite Service, version:10.2.0
の状態にもっていきました。
しかし繋がるのに10分かかります。
ver7.0.3では1,2分で繋がります。
sudo candy network show で
[ERROR] CANDY Board Service isn’t running
と表示されますが
sudo candy service status でみると
Active: active (running) と表示されます。

ログです。

ご質問ありがとうございます。
ソフトウェア環境の違いが何かしらの挙動の差異として出ていると推測しておりますが、残念ながら原因を特定できておりません。
しかしながらCANDY Pi Liteサービス以外の何らかのソフトウェアとの競合の可能性を踏まえその影響を除外するために、可能であればCANDY Pi Lite専用OSイメージをお試しいただけますでしょうか。以下のリストの最新のものをお使いいただければと思います。

こちらでも同様に10分以上接続がかかってしまうかどうかご確認いただければと思います。
