据我了解,19.04 目前仍受支持,没有其他可升级的版本。我尝试使用解决方案此处概述但那是 2014 年的事了,而且没有起到作用。
我该如何修复这个错误?
答案1
PPAhttp://ppa.launchpad.net/simonschneegans/testing/ubuntu
尚不支持 disco,但他们支持 cosmic。
让我们修复这个问题...
使用 搜索要编辑的适当 .list 文件,grep -i simonschneegans /etc/apt/sources.list.d/*.list
然后使用 编辑 {found_file_name}sudo -H gedit /etc/apt/sources.list.d/found_file_name.list
并更改迪斯科到宇宙的。
