尝试安装 Wine 时，终端会回答错误的路径：
E: Unable to locate package winehq-stable
但 它已安装：
anatoly@anatoly-desktop:~$ sudo apt install --install-recommends winehq-stable
Reading package lists... Done
请问如何告诉终端去它的位置？
anatoly@anatoly-desktop:~$ wget -nc https://dl.winehq.org/wine-builds/winehq.key

它的意思是“用户”吗？我试图通过导航到 usr cd但是我收到No such file or directory错误。
我只能用俄语找到以下信息：
"/usr (?? ????. 用户系统资源 — ????????? ??????? ????????????) — ????? ?? ? UNIX-???????? ????????, ?????????????????????? ???????????????, ???????????????????????? ?????????, ??????? ?????????????????????. ? ???????????? ? FHS, ?????????????? ????????????????????????????????????????????????????????????? ??????????????????????????? (?? ?????? /usr ? ??????????????????? ????????????????????????????????? ?? ??? ??????????????????)[1]。
???????????? ??????? ???????????? /usr/ ????????? ????????? ？？？？？？？？？????????????; ????????? ???????????? ?????????????????? ？？？？？？？？？? ??????, ???????????? ? ???????????????????????? ？？？？？？。????? ？？？???????????? ?? ？？？？？？？？？？？？？？？？？？? ？？？????? ？？？？？？？？？？？？?????[2]。/usr/bin/"
然而，我不明白。
报价的翻译：
/usr（来自英文“用户系统资源”） - 类 UNIX 系统中的目录/目录，包含动态组合的程序、用户文件和手动安装的程序。根据 FHS，它被挂载在根文件系统上，并且必须只包含不被程序修改的数据（也就是说，操作模式下的 /usr 可以被挂载为只读而不会丢失功能） …
