所以我sudo apt-get autoremove gnome-terminal安装了 alacritty。之后我检查了更新，然后sudo apt-get full-upgradePopOS 安装了 Xterm。为什么会发生这种情况？ Xterm 的图标也有“5050”覆盖图标 png 图像。
答案1
可能apt-get full-upgrade会安装Xterm，因为它可能包含在默认包中。
还：
full-upgrade (apt-get(8))
full-upgrade performs the function of upgrade but will remove currently installed packages if this is needed to upgrade the system as a whole.
