This article introduces how ubuntu12.04 installs the flash plug-in for Firefox. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

After installing Ubuntu12.04, I used Firefox to watch videos. As a result, the browser prompts that the appropriate plug-in is missing and cannot be played. In the installation wizard, I chose the adobeflash plug-in.

However, after waiting for half an hour, the flash plug-in has not yet been downloaded, because there are other software to download, so I click cancel to download the flash plug-in, only to get stuck there half an hour later:

I think, since the software center cannot be downloaded, use the apt-get install command in the terminal to download it. Results:

The code is as follows:

E: unable to acquire lock / var/lib/dpkg/lock- open (11: resource temporarily unavailable)

E: unable to lock the management directory (/ var/lib/dpkg/). Is there another process occupying it?

I closed the Ubuntu software center for a while, and then unlocked it in the following way:

The code is as follows:

Sudo rm / var/cache/apt/archives/lock

Sudo rm / var/lib/dpkg/lock

After unlocking it, I used the apt-get command to download the software again:

"E: dpkg is interrupted, you must manually run sudo dpkg-- configure-a to resolve this problem."

At this point, if you look at the Ubuntu Software Center, there is no download item "being cancelled". Use apt-get to install the software in the terminal again.

Then, I use the method provided by Yuntianhe _ reincarnation: first download install_flash_player_11_linux.i386.tar.gz on the Adobe official website, decompress it to the desktop, and install it in the terminal:

The code is as follows:

Cd'/ home/myd/ Desktop'

Tar-zxv install_flash_player_11_linux.x86_64.tar.gz

Sudo cp libflashplayer.so / usr/lib/mozilla/plugins # if this command doesn't work, (the Firefox flash plug-in for Ubuntu 12.04 may not be installed in the mozilla path:

When I installed flash today, mozilla is not valid. Change the mozilla of that command to firefox.

But it's either mozilla or firefox anyway.

If the sudo cp libflashplayer.so / usr/lib/mozilla/plugins command does not work on your computer, try the following command:

The code is as follows:

Sudo cp libflashplayer.so / usr/lib/firefox/plugins

Sudo cp-r usr/* / usr

In this way, I successfully installed the flash plug-in. Then I installed the compizconfig Settings Manager using sudo apt-get install compizconfig-settings-manager

This is how ubuntu12.04 installs the flash plug-in for Firefox. I hope the above content can be of some help and learn more. If you think the article is good, you can share it for more people to see.
