Ubuntu: Update errors Ubuntu 14.04


For a while after using the update manager, each time I get a message saying "the installation or removal of a software package failed." When using a lot of apt-get commands I also get an error similar to:

Setting up plymouth-theme-ubuntu-text (0.8.8-0ubuntu17.1) ...  sed: can't read /lib/plymouth/themes/ubuntu-text/ubuntu-text.plymouth.in: No such file or directory  dpkg: error processing package plymouth-theme-ubuntu-text (--configure):      subprocess installed post-installation script returned error exit status 2  Errors were encountered while processing:      plymouth-theme-ubuntu-text  E: Sub-process /usr/bin/dpkg returned an error code (1)  

At the end. How can I resolve this? Thanks in advance. If any other output tests need to be done I'd be happy to do so.


You can re-install plymouth-theme-ubuntu-text by running the following in a terminal:

sudo apt-get remove plymouth-theme-ubuntu-text  sudo apt-get install plymouth-theme-ubuntu-text  sudo apt-get update  sudo apt-get upgrade  

Hopefully, that should fix the issue.


First try the commands below

sudo apt-get update  sudo apt-get install --reinstall plymouth-theme-ubuntu-text  

If the error persists, follow the next steps

  1. Open the file plymouth-theme-ubuntu-text.postinst in an editor

    sudo nano /var/lib/dpkg/info/plymouth-theme-ubuntu-text.postinst  
  2. Search this code, should be start at line 21

    sed -re \          "/\[ubuntu-text\]/ {                  N;                  s/(title=Ubuntu ).*\$/\1$(lsb_release -rs)/          }" /lib/plymouth/themes/ubuntu-text/ubuntu-text.plymouth.in \                  > /lib/plymouth/themes/ubuntu-text/ubuntu-text.plymouth  
  3. Add an # before each line

    # sed -re \  #        "/\[ubuntu-text\]/ {  #                N;  #                s/(title=Ubuntu ).*\$/\1$(lsb_release -rs)/  #        }" /lib/plymouth/themes/ubuntu-text/ubuntu-text.plymouth.in \  #                > /lib/plymouth/themes/ubuntu-text/ubuntu-text.plymouth  
  4. Save the file

  5. Start the command below

    sudo apt-get install --reinstall plymouth-theme-ubuntu-text  

That's all


I had a similar issue and none of the solutions worked until I found it on the ubuntu forum in French, solution provided by "f.x0":

sudo rm -f /var/lib/dpkg/info/plymouth-theme-ubuntu-text.postinst    sudo apt-get clean    sudo apt-get update  

hope this helps!
