E: The repository 'https://ppa.launchpadcontent.net/shutter/ppa/ubuntu jammy Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

见上文错误:6。我试着做一次ppa-清洗：

sudo ppa-purge ppa:shutter/ppa
Updating packages lists
E: The repository 'https://ppa.launchpadcontent.net/shutter/ppa/ubuntu jammy Release' does not have a Release file.
Warning:  apt-get update failed for some reason

显然我做错了什么，但我不知道是什么。如有任何建议，敬请见谅。

Answer 1

ppa-purge命令的目标无效。

有问题的PPA是ppa:shutter/ppa。

若要删除它，请使用：

sudo ppa-purge ppa:shutter/ppa

假设没有其他问题，您可以更新系统：

sudo apt update
sudo apt upgrade
