I think most people press the upgrade button so the system will be up to date, but it takes some time before a new install is upgraded. New installs should have the newer ca-certificates package unless you have an older focal USB-stick, etc.
You got it exactly right! I was running from a focal flash drive (without updates) while waiting for a new SSD to replace a bad hard drive. It arrived today and after a fresh focal install to the SSD and updates, OpenModelica install ran flawlessly.
Sorry for the bother, but maybe my missteps will help someone in the future.
That worked. Thanks!
Is the ca-certifcates install/update obvious to most Linux users or should it be included in the install instructions? My Linux/Unix knowledge is a bit outdated. I'm using a fresh install of the LTS without any changes.
I'm still having some other issues, but I'll try to work through them while updating my Linux knowledge.
Hi all. Is anyone else having issues installing following the install instructions for Lunux?
Here's what I get when doing apt update:
Code:
ubuntu@ubuntu:~$ sudo apt update
Ign:1 cdrom://Ubuntu 20.04.3 LTS _Focal Fossa_ - Release amd64 (20210819) focal InRelease
Hit:2 cdrom://Ubuntu 20.04.3 LTS _Focal Fossa_ - Release amd64 (20210819) focal Release
Hit:4 http://archive.ubuntu.com/ubuntu focal InRelease

Get:6 http://archive.ubuntu.com/ubuntu focal-updates InRelease [114 kB]
Ign:7 https://build.openmodelica.org/apt focal InRelease
Err:8 https://build.openmodelica.org/apt focal Release

Here is the output from the apt-key fingerprint step:
Code:
ubuntu@ubuntu:~$ apt-key fingerprint
/etc/apt/trusted.gpg
--------------------
pub rsa2048 2010-06-22 [SC]
D229 AF1C E5AE D74E 5F59 DF30 3A59 B536 6497 0947
uid [ unknown] OpenModelica Build System <build@openmodelica.org>
sub rsa2048 2010-06-22 [E]
Subsequent steps fail also.
Am I missing something?
Thanks in advance,
Kent
