I am trying to install Seamonkey.

I am using the method shown here.

Why isn't Mozilla SeaMonkey available in the repositories? How can I install it?

When I try to do the key command, my connection times out.

andy@7:~$ sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com C1289A29
Executing: /tmp/apt-key-gpghome.mMHsuyF3KI/gpg.1.sh --recv-keys --keyserver keyserver.ubuntu.com C1289A29
gpg: keyserver receive failed: Connection timed out

2/20/19 I just found out that

The repository 'http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all Release' is not signed.

How can I get it signed?

It looks like firewall blocking port 11371 which is used by gpg. Force it to use port 80 to get gpg key.

sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 C1289A29

Alternate Command

gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys C1289A29 
  • This won't fix the first problem, that the keyserver receive timed out.

  • @Ketan Patel It added the gpg key. After sudo apt-get update, I did sudo apt-get install seamonkey-mozilla-build and got E: Unable to locate package seamonkey-mozilla-build

I got Seamonkey installed. :-)

I found the debian package here.

Not sure it will check for updates.
