Ubuntu upgrade to 14.04

After a day, the company's network has finally successfully upgraded ubuntu from 1310 to 1410, and many problems have been encountered in the middle. record the problem to prepare the participating company's network, after one day, I finally successfully upgraded ubuntu from 13.10 to 14.10, and there were many problems in the middle. I recorded them for reference. in 13.10, I wanted to try a Sogou Input Method. as a result, the fcitx version is too low and many methods are used, the fuse cannot be installed. as a result, people seem to only support the LTS version. once you upgrade the SDK, install it immediately. this blog post is written using the Sogou Input method. in 13.10, the source provided by ubuntu.cn99.com is used. I didn't think much about using this source for upgrading. open the terminal and enter the following command: $ sudo apt-get update & sudo apt-get upgrade after the system is updated, the system upgrade $ sudo do-release-upgrade encountered such a problem during the upgrade: Failed to fetch gzip:/var/lib /... hash Sum mismatchgoogle: run sudo rm-fR/var/lib/apt/lists/* sudo apt-get update. so the result of returning the source to the Main Server is still so because the downloading speed from the MainServer is too slow. maybe some packages will be dropped by the Wall. in desperation, let ubuntu help me hoose best server, mirrors.shlug.org/ubuntu.is selected, and then execute $sudo do-release-upgrade. the installation is complete.
