看: http://manpages.ubuntu.com/manpages/xenial/man8/dkms.8.html
链接中指出:
remove [module/module-version] [-k kernel/arch] [--all] Removes a module/version or module/version/kernel/arch combination from the tree. If the module is currently installed, it first uninstalls it and if applicable, will replace it with its original_module. Use the --all option in order to remove all instances for every kernel at once.
由于您要删除的模块没有与之关联的内核,因此删除它的命令是:
dkms remove rtl88x2bu/5.2.4.4 --all
您只需指定即可module/version
从--all
系统中完全删除模块。
