linux flash chrome issue: The China firewall is a shame

update2016


firefox flash可以直接

update-flashplugin-nonfree --install

因为现在已经迁移到debian平台下，这里给出一些源代码信息作为权威参考。
当然前提是计算机系统被墙，没有办法的情况下，自己到镜像下载一个deb64bit文件，然后本地操作也可以流畅用flash

自己也可以解压看update-pepperflashplugin-nonfree脚本文件关于install执行的代码段

if [ -f $cachedir/$debfile ]
            then
                cp -p $cachedir/$debfile .
            fi

            if [ ! -f $debfile ]
            then
                wgetoptions="$wgetalways $wgetprogress"
                [ "$quiet" != "yes" ] || wgetoptions="$wgetquiet $wgetalways"
                [ "$fast" != "yes" ] || wgetoptions="$wgetoptions $wgetfast"
                wgetoptions="$wgetoptions -O $UNPACKDIR/$debfile" # to change wget message : Saving to ...

                HOME=/root wget $wgetoptions $deburl || die_hard_with_a_cleanup "wget failed to download $deburl"

                [ `stat --format=%s $debfile` = "$debsize" ] || die_hard_with_a_cleanup "rejecting $debfile : wrong size"
                [ `sha1sum $debfile|sed -e "s, .*,,"` = "$debsha1" ] || die_hard_with_a_cleanup "rejecting $debfile : wrong sha1sum"
                [ `md5sum $debfile|sed -e "s, .*,,"` = "$debmd5" ] || die_hard_with_a_cleanup "rejecting $debfile : wrong md5sum"
            fi

            dpkg-deb -x $debfile unpackchrome

            sofile=unpackchrome/opt/google/chrome/PepperFlash/libpepflashplayer.so
            [ -e $sofile ] || sofile=unpackchrome/opt/google/chrome-unstable/PepperFlash/libpepflashplayer.so
            [ -e $sofile ] || sofile=unpackchrome/opt/google/chrome-beta/PepperFlash/libpepflashplayer.so
            [ -e $sofile ] || sofile=unpackchrome/opt/google/chrome/PepperFlash/libpepflashplayer.so

            mv -f $sofile /usr/lib/pepperflashplugin-nonfree
            chown root:root /usr/lib/pepperflashplugin-nonfree/libpepflashplayer.so
            chmod 644 /usr/lib/pepperflashplugin-nonfree/libpepflashplayer.so

            jsonfile=unpackchrome/opt/google/chrome/PepperFlash/manifest.json
            [ -e $jsonfile ] || jsonfile=unpackchrome/opt/google/chrome-unstable/PepperFlash/manifest.json
            [ -e $jsonfile ] || jsonfile=unpackchrome/opt/google/chrome-beta/PepperFlash/manifest.json
            [ -e $jsonfile ] || jsonfile=unpackchrome/opt/google/chrome/PepperFlash/manifest.json

            if [ -e $jsonfile ]
            then
                mv -f $jsonfile /usr/lib/pepperflashplugin-nonfree
                chown root:root /usr/lib/pepperflashplugin-nonfree/manifest.json
                chmod 644 /usr/lib/pepperflashplugin-nonfree/manifest.json
            fi

            mv $debfile $cachedir
        fi

=========
直接安装官方的chrome是最简单的办法，能够省事

不过使用linux系统自带的浏览器会干净一些，至少没有官方的广告跟踪程序。
这个时候就需要安装flash插件了，参考pepflash ppa；

add-apt-repository ppa:skunk/pepper-flash
apt-get update;
apt-get install pepflashplugin-installer

如果被墙，会出现网络错误提示

IOError: [Errno socket error] [Errno 101] Network is unreachable
Setting up pepflashplugin-installer (16.0.0.235~cr39.0.2171.95-1-0skunk0) ...

不过你可以手动下载chrome amd64 linux安装包，可以参考技术点
