skp Bugs, Ubuntu 19.10 Leave a comment

I keep seeing this message periodically when launching things from the command line. For example, I launched keepass2, and I get this message:

Gtk-Message: 20:24:04.576: Failed to load module "canberra-gtk-module"

Here’s the simple fix … install the libcanberra-gtk-module. Here’s the command-line:

sudo apt install libcanberra-gtk-module

That fixed my problem! Note: the only symptom was just the warning on the console. I didn’t notice any other issues caused by not having that module.

JPG Loading Issue

skp Troubleshooting Leave a comment

Unfortunately, this issue is unsolved for me. I found plenty of things that fixed it for other people, so maybe they will help you. If you have an idea of something else to try, please comment.

My laptop will not load jpeg files for some reason. Chrome and Internet browsing works just fine. I can see all images there, but I can’t see jpeg images in Eye of Gnome. The worst is that I can’t see the background. The desktop background is just blue.

Here’s my troubleshooting notes:

Open SSL Weak Certificate

skp Networking, VPN Leave a comment

I have a client’s VPN that was giving me a hard time. It was an Open VPN connection.

There was a comment in the Forum that I was reading about security. It sounds like it would be better to regenerate the certificates, but since I have no control over the server, I couldn’t do that.

Error Messages

There are the error messages that I was seeing in my log:

  • Cannot load certificate file <path removed>COTVPN.crt
  • OpenSSL: error:140AB18E:SSL routines:SSL_CTX_use_certificate:ca md too weak
  • Options error: Please correct these errors.

I checked my version:

$ openvpn --version
OpenVPN 2.4.4 x86_64-pc-linux-gnu [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] [PKCS11] [MH/PKTINFO] [AEAD] built on Feb 10 2018

Solution

First, I edited the VPN’s configuration file:

 sudo vi /etc/NetworkManager/system-connections/COTVPN

As the last line under the [vpn] section, I added the line:

tls-cipher=DEFAULT:@SECLEVEL=0

Then, I ran this command to reload the configuration:

sudo nmcli connection reload

After that, it worked.

Missing Packages

Note: Earlier, I was getting these messages:

  • VPN plugin at /usr/lib/NetworkManager/nm-iodine-auth-dialog is not executable
  • VPN plugin at /usr/lib/NetworkManager/nm-vpnc-auth-dialog is not executable

I installed these two packages:

  • network-manager-iodine-gnome
  • network-manager-vpnc-gnome

Those two packages fixed those errors.

Remmina Package Issue

skp remmina, Troubleshooting Leave a comment

Just after install, I ran into an issue with Remmina not connecting with remote desktop. Come to find out, one of the previous steps I had taken had uninstalled the remmina-plugin-rdp package. I was able to download it and install it, but it broke apt-get.

Here’s the error message:

sudo apt install remmina remmina-plugin-rdp remmina-plugin-vnc remmina-plugin-nx
[sudo] password for skp: 
Reading package lists... Done

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libgoo-canvas-perl : Depends: libextutils-depends-perl but it is not going to be installed
                      Depends: libextutils-pkgconfig-perl but it is not going to be installed
 remmina : Depends: remmina-common (= 1.2.30+ppa201805311012.rabac8fe.dc846e39~ubuntu18.04.1) but 1.2.30+ppa201805301643.rabac8fe.d627b4d9~ubuntu18.04.1 is to be installed
 remmina-plugin-nx : Depends: nxproxy
 remmina-plugin-secret : Depends: remmina (= 1.2.30+ppa201805301643.rabac8fe.d627b4d9~ubuntu18.04.1)
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I had previously enabled this repository.
http://ppa.launchpad.net/remmina-ppa-team/remmina-next/ubuntu

That had given me version: 1.2.30.1 (git n/a)

I disabled the repository using the software and updates GUI. Then, I ran these commands:

sudo apt-get update
sudo apt --fix-broken install

Somehow it was enabled again. So, it seems it is fixed even with that repository.
