在Ubuntu 16.04上通过ppa升级到Chrome 61.0.3163但由于NSS已过期而无法启动

我在Ubuntu 16.04上通过ppa升级到Chrome 61.0.3163,但由于NSS过时而无法启动。 在终端中启动Chrome可以:

NSS >= 3.26 is required. Please upgrade to the latest NSS, and if you still get this error, contact your distribution maintainer. 

运行

 sudo apt-get install libnss3 

 libnss3 is already the newest version (2:3.21-1ubuntu4) 

我是否应该尝试获取不在存储库中的更新版本的libnss? 我暂时降级了我的Chrome版本。

您的计算机未运行xenial-updatesxenial-security存储库。

启用存储库(取消注释这些存储库的行),然后运行sudo apt-get updatesudo apt-get dist-upgrade并将所有软件包升级到最新的软件包版本。

您的libnss3版本似乎已损坏或丢失。 尝试重新安装它

 sudo apt-get install --reinstall libnss3
