16.04 -> 18.04¶

I want to install BaiduYunpan for Linux, but actually I have tried it before, which cannot work for my current version. However, I note that the version has been updated, although it is still for Ubuntu 18.04, not Ubuntu 16.04.
Same results with the previous try, cannot start it after installing it, and no error thrown in the install procedure. But today I went further, I found that after I type
/opt/baidunetdisk/baidunetdisk
it throws an error,
This program requires version 3.3.0 of the Protocol Buffer runtime library, but the installed version is 2.6.1.
Try to install latest version from protocolbuffers/protobuf, first time the latest one, 3.14, but it doesn’t work and it require .so.9, while v3.14 has a .so.22, I also tried copy .so.22 to .so.9, or make a soft link, doesn’t work. The second time I install v3.3, the .so.[NUM] still does not match, and hence doesn’t work.
The error is
libmirprotobuf.so.3: undefined symbol: _ZNK6google8protobuf11MessageLite25InitializationErrorStringB5cxx11Ev
and then I follow the instructions in Ubuntu: mir package
sudo apt-get purge libprotobuf-lite9v5
sudo apt-get install libprotobuf-lite9v5
the first step throws the dependencies warnings, related to libqt5, then I uninstall libqt5. Unfortunately, many running programs then exit when the uninstalling procedure keeps going, and I found that I make a big mistake!!
Now, maybe the best way is to update my system from Ubuntu 16.04 to Ubuntu 18.04 to recover the broken system. Actually I have updated my old PC from 16.04 to 18.04, seems quite fluent.
However, for this PC, there are many disappointing problem.
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt autoremove
it is necessary to modify /etc/update-manager/release-upgrades from never to lts, otherwise it cannot detect new release version. Then run
sudo do-release-upgrade
refer to 将 Ubuntu 16.04 LTS 升级到 Ubuntu 18.04 LTS
Due to previous HK Ubuntu mirror, the speed is quite slow, then the first thing I need to do is to replace the mirror in /etc/apt/sources.list with aliyun by sed operation via
sudo sed -i "s#http://ftp.cuhk.edu.hk/pub/Linux/ubuntu/#http://mirrors.aliyun.com/ubuntu/#" sources.list
后来更新至，
sudo sed -i "s#ftp.cuhk.edu.hk/pub/Linux#archive.ubuntu.com#g" sources.list
Then go on. However, I mistook enter something in the middle, and stop the installation procedure, that is might be part of the reason why I met so many problems.
Try to run do-release-upgrade again, but it said no new release version, and told me to upgrade the software in the current version. Actually it is Ubuntu 18.04 now, checking by
lsb_release -a
then I run
sudo apt-get update
sudo apt-get upgrade
after the first run, I think I am OK. But in the rebooting, I cannot enter into the system, the Ubuntu logo is twinkling, and sometimes I can switch to the command window, it holds with message
a start job is running for hold until boot process finishes up（X s/unlimit）
but do not want to try the re-install solution in 问题1：a start job is running for hold until boot process finishes up（X s/unlimit）, because I guess my situation would be quite different, since I uninstall libqt5, and interrupt the normal release updating procedure,
Then I found some other possible solutions,
sudo apt-get update
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install unity
But the first thing I need to do is to stop it by power, and then choose to start an advanced session in the grub session, and I chose a recovery mode, then I entered into a command line. And I can continue to fix the problem.
But before I can install the desktop, repeat to run update and upgrade, then updating texlive from 2015 to 2017 throws an error,
dpkg: error processing archive /var/cache/apt/archives/texlive-fonts-extra-doc_2017.20180305-2_all.deb (–unpack): trying to overwrite ‘/usr/share/doc/texlive-doc/latex/mweights/README’, which is also in package texlive-latex-extra-doc 2015.20160320-1 dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)
try install -f, but does not work, the solution is
sudo dpkg -i --force-all /var/cache/apt/archives/texlive-fonts-extra-doc_2017.20180305-2_all.deb
refer to 在apt更新texlive到2017的问题
then I reboot to test, but the internet broken, ifconfig only returns lo, but ifconfig -a shows all possible cards, I have tried service restart like in UBUNTU ifconfig只有lo, but it does not work, then I found the solution worked for me
sudo dhclient enp**
in Ubuntu输入ifconfig找不到IP地址，只有lo问题.
Reboot after the desktop is successfully installed, I can enter into the graphical system!!
