Ubuntu卸载dpkg安装的软件

我用dpkg安装了dropbox

sudo dpkg -i dropbox_2020.03.04_amd64.deb

现在想要卸载

sudo dpkg --purge dropbox_2020.03.04_amd64.deb

这样做不行

dpkg: error: you must specify packages by their own names, not by quoting the names of the files they come in

Type dpkg --help for help about installing and deinstalling packages [*];
Use 'apt' or 'aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;

Options marked [*] produce a lot of output - pipe it through 'less' or 'more' !

提示直接指定名字就可以了

查看安装的软件名字

dpkg -l

找到了它的名字叫 “dropbox”

sudo dpkg --purge dropbox

卸载成功了！
