安装Ubuntu18.04后，发现终端不能输入中文
$ locale -a
C
C.UTF-8
...
en_US.utf8
...
zh_CN.utf8
...
发现系统中支持zh_CN.utf8，配置下zh_CN.UTF-8字符集
在~/.bashrc中配置
exprot LC_ALL="zh_CN.UTF-8"
OK，使用没问题

配置好android编译环境后，编译android7.1.2，遇到如下错误
FAILED: /bin/bash -c "prebuilts/misc/linux-x86/flex/flex-2.5.39 -oout/host/linux-x86/obj/STATIC_LIBRARIES/libaidl-common_intermediates/aidl_language_l.cpp system/tools/aidl/aidl_language_l.ll"

看报错应该和locale相关，日期时间使用zh_CN.UTF-8字符集有问题？
看来上面配置的，在一些情况下是有问题的，继续查看系统支持的字符集
$ locale -a
C
C.UTF-8
...
en_US.utf8
...
zh_CN.utf8
...
C.UTF-8发现一个奇怪的配置，查了下和C的区别：
C = POSIX standards-compliant default locale. Only strict ASCII characters are valid.
C.UTF-8 = POSIX standards-compliant locale, extended to allow the basic use of UTF-8. No character upper-lower case relationships and collation orders defined beyond ASCII.
唔嗯符合POSIX标准，运行使用UTF-8，配置下试试
在~/.bashrc中配置
export LC_ALL=C.UTF-8
终端可以正常输入中文，然后去编译，（一段时间后）
#### make completed successfully ####
完美解决

今天重启遇到如下问题
/dev/mapper/ubuntu--vg-root contains a file system with errors, check forced.
Inodes that were part of a corrupted orphan linked list found.
/dev/mapper/ubuntu-vg-root: UNEXPECTED INCONSISTENCY; Run fsck MANUALLY.
(i.e., without -a or -p options)
fsck exited with status code 4.
The root file system on/dev/mapper/ubuntu--vg-root requires manual fsck
按照提示fsck
(initramfs) fsck /dev/mapper/ubuntu--vg-root
然后再对fix提示输入'y'修复对应的问题
