A: https://www.linuxjournal.com/content...aring-out-boot

sudo dpkg --purge $(dpkg --list "linux-image*" | grep -v \
 $(uname -r) | grep ii | awk '{ print $2 }')

Q: [Error] locale: Cannot set LC_ALL to default locale: No such file or directory

A：

#> locale
locale: Cannot set LC_ALL to default locale: No such file or directory

#> export LC_ALL="en_US.UTF-8"

#> vi ~/.profile

export LC_ALL="en_US.UTF-8"

如果出現錯誤：-bash: warning: setlocale: LC_ALL: cannot change locale (zh_TW.UTF-8)
