I installed Postgresql 9.3 for Ubuntu 14.04 trusty using this command:

sudo apt-get install postgresql-client-9.3 libpq-dev

I wanted to remove postgresql and instead install 9.2 so I ran this command

sudo apt-get install postgresql-client-9.3 libpq-dev

This yields the error:

dpkg: warning: 'ldconfig' not found in PATH or not executable
dpkg: warning: 'start-stop-daemon' not found in PATH or not executable
dpkg: error: 2 expected programs not found in PATH or not executable
Note: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin

Running sudo -i,echo $PATH yields this output:

/opt/ree/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

Regression

I've tried this command to purge it from existence but I keep getting the same error:

sudo dpkg --purge postgresql-9.3

I've looked on some forums but I haven't found the error messages that I am receiving.

I've also looked into said directores and /usr/local/sbin, /usr/sbin and /sbin exist.

What could be the problem?

  • Do sudo -i, enter your username's password, do echo $PATH, then do exit. Post the output from the command echo $PATH to your question. – Alaa Ali Aug 11 '14 at 21:42

    Search for different messages like the part "not found in PATH or not executable". The first results I see is ubuntuforums.org/showthread.php?t=1942520 and gives plenty of possibilities to try. Please also include your tries as regression in your question and/or answer. For your understand, the issue is not that /usr/sbin etcetera paths do not exist, but that the installation can't find the helper applications ldconfig and start-stop-daemon. – Pro Backup Aug 12 '14 at 11:28
  • Thanks Pro Backup. This removed the problem I was having. I had to use this command PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin sudo apt-get -f install – Dan Rubio Aug 12 '14 at 18:40

Try to include the missing directories in your path before running the apt-get.

Like:

$ PATH=$(PATH):/usr/local/sbin:/usr/sbin:/sbin
$ sudo apt-get remove postgresql-client-9.3

Note: this PATH setting will be lost after reboot. The save this setting permanently place it in your shell its rc file, for example when using BASH shell: $ nano .bashrc

If you installed it from the repositories, you could try to uninstall it trough apt-get and not dpkg:

sudo apt-get remove posgresql-client-9.3
