I just walked someone through the confusion of "Xenial or later" in #reprap yesterday. This is a much better wording and should avoid confusion.

Text updated, pre-compiled package button text updated as well to:

UBUNTU BIONIC THROUGH DISCO 64BIT

Ahh, the link I was having problems with was this one: http://devel.lulzbot.com/software/cura-lulzbot/linux/README.debian

There was confusion over which repo should be used, as they missed the table at the bottom. I propose a couple updates to this one as well.

In step 1.) Remove "For Debian Jessie 32bit" and replace with "For WIly, Vivid, Utopic, and Trusty 32 bit systems"

Repeat this for the stretch and buster repos

In step 2.) Repeat the same process for step 1. Customers don't seem to realize the architecture of their OS, and just remember the name.

Last one, maybe an update to the name of the readme file. (CD has more details on this one)

change README.debian to README
move the Ubuntu table up to a new Ubuntu Users: section, then clone the instructions tailored to ubuntu users with release names. Leave the debian section as is, but below that.

closing, Alexei's recommending only moving forward with the instructions on LulzBot.com: https://www.lulzbot.com/learn/tutorials/cura-lulzbot-edition-installation-ubuntu

I'm not sure whether this is the right place to report it, but after I recently updated my system Cura LE stopped working, and currently the instructions published here no longer work for me on Ubuntu 18.04 LTS.

I have "Ubuntu 18.04.2 LTS" according to "lsb_release -a" (amd64)

I tested 4 different entries in /etc/apt/sources.list :

  • deb http://download.alephobjects.com/ao/aodeb buster main => successfully installs 3.6.3, startup fails with "/usr/share/cura-lulzbot/cura-lulzbot: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by /usr/share/cura-lulzbot/cura-lulzbot)" [this was working previously, I believe with version 3.6.2 of Cura LE]
  • deb http://devel.alephobjects.com/ao/aodeb buster main => successfully installs 3.6.4, startup fails with "/usr/share/cura-lulzbot/cura-lulzbot: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by /usr/share/cura-lulzbot/cura-lulzbot)"
  • deb http://download.alephobjects.com/ao/aodeb stretch main => successfully installs 3.6.3, seems to work ok
  • deb http://devel.alephobjects.com/ao/aodeb stretch main => successfully installs 3.6.4, tested to work ok

libc.so.6 is from the following package:

libc6:
  Installed: 2.27-3ubuntu1
  Candidate: 2.27-3ubuntu1
  Version table:
 *** 2.27-3ubuntu1 500
        500 http://ch.archive.ubuntu.com/ubuntu bionic/main amd64 Packages

So it looks like buster has a more recent version than Ubuntu 18.04 LTS. I don't know why it was working previously.

We had a customer reach out last night about Ubuntu still having difficulties with installation. He included the issues he has found which I did my best to summarize below:

1.) Cura 3.6.3 will not install on Ubuntu 18.04 Bionic.

Bad dependency on libssl1.0.2 continues
Dependency on libc 2.8 - Ubuntu 18.04 only has libc 2.7; 2.8 did not become part of the Ubuntu distributions until 18.10 Cosmic.

2.) Cura 3.6.3 will not install on Ubuntu 19.04 Disco (Daily Build) without quite a bit of know-how:

Bad Dependency on libssl 1.0.2 continues.
Missing Dependency on libreadline7 which is not available on Disco

If you need any additional information let me know. Thanks!
