xrdp wants to remove lubuntu-desktop on lubuntu

[Kenneth Heal]

If I attempt to install xrdp on a Lubuntu 18.04.5 machine apt wants to remove lubuntu-desktop (a variant of LXDE), which would obviously disrupt the system.

Expected behaviour:

xrdp to install without attempting to remove lubuntu-desktop lubuntu-gtk-desktop and lubuntu-gtk-core.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 1923328

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709

FYI: `lubuntu-desktop` on bionic is EOL in a few days, being the last of the LXDE desktop supported by Lubuntu.

I booted a Lubuntu 18.04.5 LTS live system, and performed
`sudo update` to update software lists
`sudo apt install xrdp`
and two new packages are installed (xorgxrdp & xrdp) so I don't see an issue.

I'm going to mark this bug incomplete; as it appears you need support and I could NOT re-create the issue. Please use `ubuntu-bug` in future, but your issue is likely other software you have installed. If you believe I'm in error, or have made a mistake, please leave a comment explaining why, and you can change the status of this bug report back to "New".

[Chris Guiver (guiverc)]

Sorry I booted a focal 20.04.3 thumb-drive (comment #1) & I didn't notice in my prior test (grabbed the wrong thumb-drive for my test)

The effect of the `sudo apt install xrdp` (after `sudo apt update`) does in fact cause removal of the packages suggested by the OP (kheal/Kenneth)

however please note as stated in my last comment; `xrdp` & `lubuntu-desktop` are from 'universe' and reach EOL this month so the chance of this being fixed is extremely small.

YOU CAN HOWEVER achieve what you want with the command

`sudo apt install xrdp --no-install-recommends`

(tested this time on a bionic Lubuntu 18.04.5 live system)

[Kenneth Heal (kheal)]

Thanks for the update, I was under the impression 18.04 is an LTS release.

Anyway I think I may have solved the issue with the following:

====
So, there is a need to rebuild xrdp against HWE 18.04 on Ubuntu 18.04.2.

Maybe Ubuntu should provide a new binary package, let’s say “xrdp-hwe-18.04″…

For now, I’ve recompiled the same xrdp from Ubuntu 18.04, on Ubuntu 18.04.2 and uploaded to my “XRP PPA”, here:

https://launchpad.net/~martinx/+archive/ubuntu/xrdp-hwe-18.04

To enjoy xrdp on Ubuntu 18.04 with HWE, just do:

sudo add-apt-repository ppa:martinx/xrdp-hwe-18.04
sudo apt install xrdp xorgxrdp

Bug report:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1817225
===

In short the following steps resolved the issue:
$ sudo add-apt-repository ppa:martinx/xrdp-hwe-18.04
$ sudo apt-get install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04
$ sudo apt-get install xrdp xorgxrdp xfonts-100dpi xfonts-75dpi
$ sudo adduser xrdp ssl-cert
$ grep ^X11Forwarding /etc/ssh/sshd_config
X11Forwarding yes
$ cat ~/.xsession
#!/bin/sh

/usr/bin/lxsession -s Lubuntu -e LXDE

> I was under the impression 18.04 is an LTS release.

Yes Ubuntu 18.04 LTS, and Lubuntu 18.04 LTS were long-term-support releases, however that means 5 years for Ubuntu 18.04 LTS & 3 years for 'universe' based Lubuntu 18.04 LTS. Not all 'universe' packages however had 3 years of supported life, eg. Ubuntu Studio 18.04 was not a LTS release thus it's packages only had 9 months of supported life (as did Lubuntu Next 18.04 which likewise wasn't a LTS so had 9 months; ie. the LXQt release)

The release notes state

"Maintenance updates will be provided for 5 years for Ubuntu Desktop, Ubuntu Server, Ubuntu Cloud, and Ubuntu Core. Ubuntu Studio will be supported for 9 months. All the remaining flavours will be supported for 3 years."

(https://fridge.ubuntu.com/2018/04/27/ubuntu-18-04-lts-bionic-beaver-released/ https://lubuntu.me/bionic-5-released/)

Five years applies to 'main' repository only (ie. what was provided on the Ubuntu 18.04 LTS Server, Desktop, Cloud or Core ISOs)
