我遵循了这里的所有步骤： https://developer.ubuntu.com/en/start/ubuntu-for-devices/installing-ubuntu-for-devices/
并且所有步骤都运行正常，直到：
hmusr@hmusr:~$ ubuntu-device-flash touch --channel=ubuntu-touch/stable/ubuntu --bootstrap

上面显示的最后一行已经存在超过 12 个小时，没有任何进展。不知道该如何处理。
有谁知道解决方法吗？
答案1
您可以尝试通过以下命令清理本地缓存：“ubuntu-device-flash --cleanup-cache touch”。
此后只需重新运行 flash 命令即可。
如果这不是你第一次刷入 UbuntuTouch？那么请尝试不使用“--bootstrap”选项。
