平台
Ubuntu20.04 + VirtualBox 6.16
问题
早上开机, 突然发现virtualbox崩溃了, 历史重演, 果断卸载重装
(VB是个让人又爱又恨的东西, 折腾去解决现有的问题不如重装来得快).
下载VirtualBox 6.16安装包和扩展包后, 使用dpkg -i *.deb 失败, log 如下:
$ sudo dpkg -i virtualbox-6.1_6.1.16-140961_Ubuntu_eoan_amd64.deb

前面还缺少两个信赖包, 已安装上
sudo apt-get install libqt5opengl5 libqt5printsupport5
Python版本问题
很奇怪的问题是提示的python(2.7 <= 要求版本 << 2.8)包都已正确安装, 但就是找不到
# 当前版本 $ sudo python --version Python 2.7.18 $ sudo which python /usr/bin/python $ ll /usr/bin/python lrwxrwxrwx 1 root root 18 11月 3 09:13 /usr/bin/python -> /usr/bin/python2.7* $ ll /usr/bin/python2.7 -rwxr-xr-x 1 root root 3629032 8月 4 19:16 /usr/bin/python2.7* # 其它信息: $ ll /usr/bin/python* lrwxrwxrwx 1 root root 18 11月 3 09:13 /usr/bin/python -> /usr/bin/python2.7* lrwxrwxrwx 1 root root 9 3月 13 2020 /usr/bin/python2 -> python2.7* -rwxr-xr-x 1 root root 3629032 8月 4 19:16 /usr/bin/python2.7* lrwxrwxrwx 1 root root 9 11月 2 18:22 /usr/bin/python3 -> python3.8* -rwxr-xr-x 1 root root 5486352 7月 28 20:59 /usr/bin/python3.8* lrwxrwxrwx 1 root root 33 7月 28 20:59 /usr/bin/python3.8-config -> x86_64-linux-gnu-python3.8-config* lrwxrwxrwx 1 root root 16 3月 13 2020 /usr/bin/python3-config -> python3.8-config* -rwxr-xr-x 1 root root 384 3月 28 2020 /usr/bin/python3-futurize* -rwxr-xr-x 1 root root 388 3月 28 2020 /usr/bin/python3-pasteurize*
搜索一番后找到 [Solved ]Python2 dependency hell, 装上 python-is-python2可以解决
$ sudo apt install python-is-python2
装上后, /usr/bin下的python发生了变化:
$ ll /usr/bin/python* lrwxrwxrwx 1 root root 7 4月 15 2020 /usr/bin/python -> python2* lrwxrwxrwx 1 root root 9 3月 13 2020 /usr/bin/python2 -> python2.7* -rwxr-xr-x 1 root root 3629032 8月 4 19:16 /usr/bin/python2.7* lrwxrwxrwx 1 root root 9 11月 2 18:22 /usr/bin/python3 -> python3.8* -rwxr-xr-x 1 root root 5486352 7月 28 20:59 /usr/bin/python3.8* lrwxrwxrwx 1 root root 33 7月 28 20:59 /usr/bin/python3.8-config -> x86_64-linux-gnu-python3.8-config* lrwxrwxrwx 1 root root 16 3月 13 2020 /usr/bin/python3-config -> python3.8-config* -rwxr-xr-x 1 root root 384 3月 28 2020 /usr/bin/python3-futurize* -rwxr-xr-x 1 root root 388 3月 28 2020 /usr/bin/python3-pasteurize*
再次安装VirtualBox, 成功.
