I am facing a problem which seems to be unsolvable. I am trying to resolve the issue but to my disappointment nothing seems to work. The problem I'm facing are as follows

  1. Whenever I try to run sudo apt-get install or sudo apt-get update, I get the following error :

    apt-get: error while loading shared libraries: libapt-pkg.so.4.12: cannot open shared object file: No such file or directory

  2. To resolve this issue I downloaded libapt-pkg.so.4.12 and ran command sudo dpkg -i libapt-pkg.so.4.12.deb it gives error

    dpkg: error processing libapt-pkg4.12_1.0.9.7ubuntu4_i386.deb (--install):  cannot access archive: No such file or directory
Errors were encountered while processing: libapt-pkg4.12_1.0.9.7ubuntu4_i386.deb

  • OK. Why did you download `i386` package? I fixed the command. But it looks that you have it installed already. You should use the solution only for your architechture `amd64` in the other answer. But you seem to do both. – Pilot6 Sep 15 '15 at 10:21

  1. Download the deb file for Precise

    cd; wget http://mirrors.kernel.org/ubuntu/pool/main/a/apt/libapt-pkg4.12_0.8.16\~exp12ubuntu10.25_amd64.deb

  2. Extract the deb file

    dpkg -x libapt-pkg4.12_0.8.16\~exp12ubuntu10.25_amd64.deb deb

  3. Copy the files

    sudo cp deb/usr/lib/x86_64-linux-gnu/libapt-pkg.so.4.12.0 /usr/lib/x86_64-linux-gnu/libapt-pkg.so.4.12.0

  4. Create a symbolic link

    sudo ln -s /usr/lib/x86_64-linux-gnu/libapt-pkg.so.4.12.0 /usr/lib/x86_64-linux-gnu/libapt-pkg.so.4.12

  5. After the files are available again, your package system will work again. You should re-install the package libapt-pkg4.12 anyway

    sudo apt-get install --reinstall libapt-pkg4.12

  • I am using Ubuntu 12.04 LTS, 64-bit machine with Intel® Core™ i3-4005U CPU @ 1.70GHz × 4 Processor – Abhijeet yadav Sep 15 '15 at 09:58
  • Why not just install the deb by `dpkg -i`? – Pilot6 Sep 15 '15 at 10:00
  • @Pilot6 -_- sure :\ – A.B. Sep 15 '15 at 10:03
  • Hey @A.B, Thank you for your reply. I did what you as you said. Everything was fine except the execution of the last command. The last command when executed gives Error. – Abhijeet yadav Sep 15 '15 at 10:04
  • Which error do you mean? – A.B. Sep 15 '15 at 10:12
  • You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: libapache2-mod-auth-mysql : Depends: apache2.2-common (>= 2.2.3-3) but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). – Abhijeet yadav Sep 15 '15 at 10:15
  • @A.B. please remove 32-bit solution. It confused the OP. – Pilot6 Sep 15 '15 at 10:22
  • @pilot, I pasted every command for 64 bit machine. I dont't know why it is showing error for 32 bit pkg – Abhijeet yadav Sep 15 '15 at 10:25
  • Because you have downloaded `i386` package. Look into your Home folder. – Pilot6 Sep 15 '15 at 10:26
  • I remove i386 and run the command, but the same error persist.--------------You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: libapache2-mod-auth-mysql : Depends: apache2.2-common (>= 2.2.3-3) but it is not going to be installed E: Unmet dependencies.

  • @Abhijeetyadav That's a completely different problem. Try `sudo apt-get install -f` If this doesn't work, ask a new question – A.B. Sep 15 '15 at 10:43
  • @Pilot6 I have the part removed. – A.B. Sep 15 '15 at 10:59
