我正在使用 Lubuntu 19.10，我想安裝 jitsi meet。我按照以下步驟操作：https://jitsi.org/downloads/ubuntu-debian-installations-instructions/。哪個是：
wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | sudo apt-key add -
然後
sudo sh -c "echo 'deb https://download.jitsi.org stable/' > /etc/apt/sources.list.d/jitsi-stable.list"
然後
sudo apt-get -y update
最後
sudo apt-get -y install jitsi-meet
但是，在該過程結束時我收到以下錯誤：
dpkg: error processing package jitsi-meet-web-config (--configure):
installed jitsi-meet-web-config package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
jitsi-meet-web-config
E: Sub-process /usr/bin/dpkg returned an error code (1)
我該如何解決這個錯誤？
