软件更新程序需要更多磁盘空间

Jaa*_*älä 10 disk-usage 14.04

我从软件更新程序收到以下错误消息:

The upgrade needs a total of 74,6 M free space on disk '/boot'. Please free at least an additional 68,3 M of disk space on '/boot'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'.

我在 Ubuntu 14.04 上遇到了同样的消息。这个问题的答案通过从 /boot 中删除旧的 Linux 内核来解决这个问题。它释放了几乎一半的空间。
