Synaptic Won't Open

sdenethor · 05-07-2016, 11:42 AM

Synaptic worked fine for several months after installing pclinuxos. However, since the last software update, Synaptic won't open. When trying to open Synaptic, it asks for my root password. I enter the password, the password dialog disappears, and Synaptic never opens.

Terminal (root) isn't recognizing apt-get, either.

Is there a way to fix this without having to do a full re-install? I have not seen this exact issue on any of the forums I follow.

It is easiest too see errors when you run graphical programs from the terminal.

Code:

type -all synaptic
type -all apt-get
echo $PATH

sudo synaptic

What is the output of the above commands?

Both -all and -sudo commands result in "command not found" error messages in Terminal.

That's not clear. Can you copy/paste the literal commands you typed and error messages from now on? Please make use of forum formatting when you do (like code and quote blocks).

type and echo are shell built-ins for bash so if you're using bash it should output something.

Note the command is not -all but literally "type -all". When you see text in a code block it generally means you type all of it.

OK, here are the actual code results. I'm using LXTerminal.

OK, what you get in response to

Code:

apt-get update

?

sdenethor · 05-07-2016, 03:00 PM

This is the result:

Code:

[root@localhost person]# type apt-get update
apt-get is /usr/bin/apt-get
bash: type: update: not found

Emerson · 05-07-2016, 03:14 PM

Not what I asked.

sdenethor · 05-07-2016, 03:26 PM

OK, here it is.

Code:

[root@localhost person]# apt-get update
apt-get: symbol lookup error: /lib64/libnssutil3.so: undefined symbol: PR_GetEnvSecure

sag47 · 05-07-2016, 03:31 PM

Are you logged in as root? The # tells me so. Instead, just execute on the terminal.

Code:

synaptic

Looks like interrupted upgrade, is dpkg still working?

sdenethor · 05-07-2016, 03:52 PM

This is what the code shows. Once the command runs, it opens the Synaptic password dialog. I enter the password, and Synaptic does not load.

Code:

[person@localhost ~]$ synaptic
/usr/libexec/synaptic: symbol lookup error: /lib64/libnssutil3.so: undefined symbol: PR_GetEnvSecure

sdenethor · 05-07-2016, 04:14 PM

Doesn't seem to be working...

Code:

[person@localhost ~]$ dpkg
bash: dpkg: command not found

Emerson · 05-07-2016, 05:16 PM

It probably needs to be run by root, if I remember correctly from my Debian days dpkg is the tool apt-get is using. As long as dpkg works you can fix your Linux.

sdenethor · 05-07-2016, 06:40 PM

Same message in root...

Code:

[root@localhost person]# dpkg
bash: dpkg: command not found
