I trying to install Ruby 2.2.3 in Ubuntu 21.04 with rvm but I get stuck in the dependencies, libssl1.0-dev. I tried some tips found in this link:
Edit this file /etc/apt/sources.list and add this line to the end of it.
deb http://security.ubuntu.com/ubuntu bionic-security main
After that run:
sudo apt update && apt-cache policy libssl1.0-dev
But I get stuck in two errors:
First when I not add the trusted option in sources.list:
Err:3 http://security.ubuntu.com/ubuntu xenial-security InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 NO_PUBKEY 3B4FE6ACC0B21F32
Hit:9 http://br.archive.ubuntu.com/ubuntu hirsute-backports InRelease
Reading package lists... Done
W: GPG error: http://security.ubuntu.com/ubuntu xenial-security InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 NO_PUBKEY 3B4FE6ACC0B21F32
E: The repository 'http://security.ubuntu.com/ubuntu xenial-security InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
Second when i add the trusted option in the sourcers.list file:
W: GPG error: http://security.ubuntu.com/ubuntu bionic-security InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3B4FE6ACC0B21F32
libssl1.0-dev:
Installed: (none)
Candidate: 1.0.2n-1ubuntu5.6
Version table:
1.0.2n-1ubuntu5.6 500
500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages
After that I will not be able to continue, every time that I run
sudo apt-key adv --keyserver keyserver.ubuntu.com. --recv-keys 3B4FE6ACC0B21F32
I will receive this error
Server indicate a failure
I tried with other servers like:
- hkp://ipv4.pool.sks-keyservers.net
- hkp://pgp.mit.edu
- hkp://keyserver.pgp.com
But none of them worked, someone can help me?
