I wonder if we'll ever get /usr/bin/python back. Or is it going to be like browser user-agent strings where we call it "python3" forever and forget why we can't just call it python?

I think the python team decided to do it that way, in combination with various distro?

Was anyone able to run 18.04 or 20.04 successfully on a relatively modern desktop spec (AMD Ryzen 9 3950X / Nvidia 2080 TI / 32GB RAM / Custom water cooling) and two displays? I'm thinking of upgrading my development machine and running ubuntu only and I'm looking for some hints as to what could go wrong.

Running an i5 9600K / 2x Nvidia 2070 / 64GB RAM on 19.10 and I managed to get to a fairly stable configuration. The only pain point was and has always been Nvidia drivers and CUDA stability. I have yet to find a consistent way to install the driver and CUDA version you want and lock them. A couple of weeks ago I installed Wine which deleted my CUDA packages. For now it's stable enough for a few months until I need to reinstall or tinker with something but maybe someone has suggestions for improving stability.

Most reviews are very positive. Faster, better, Amazon removed, maybe the best Ubuntu release until now. The only 'con' is the pushing of Snap packages. It looks like deb files only can be installed via the terminal. Ubuntu is also researching if they can get Adobe on board. I doubt this would ever happen, but that would be huge. Most people stick on Windows and MacOS because Adobe software is not available on Linux.…

This is why I don't bother installing snaps unless the developer themselves are actually providing(or at least promoting) the snap. There's been a couple of occasions where I went to install the snap and it turned out to either be an old or broken version of the software.

I don't have too many technical quibbles with snaps, it's just the way Ubuntu has the ecosystem setup now.

I've been running the last "nightly" release or whatever it is of 20.04 since Apr 20 on the same specs you list (3900x instead of 3950x). No problems so far on my ultrawide 3440x1400 display or with the proprietary nvidia driver. Just choose the 'safe' graphics option on boot of the live usb.

I understand the hate for snap (and flatpak) and I personally use deb as much as I can, but they are the right move. Yes, right now it's a subpar experience. But you need to deploy it now to be able to improve on it and have it as the default in the future. And I believe it's a better future, because: - packaging a deb is difficult. I've done it, and it's a lot of complicated hard work you get to repeat for every rel…

I think Snap is a great way forward. I get the argument that shared libraries let you update one package to get a fix for the entire system without relying on any number of maintainers to independently stay on top of security issues, but in practice it doesn't work all that well and makes things more complicated. Maybe Nix improves this; I've been meaning to play with it for years.

From a distributor perspective, I love that it was simple and publishing at https://snapcraft.io/cyph gets us on every distro with no hassle. The alternative was likely not supporting Linux at all right away, or at best supporting a couple distros and requiring more work on the user end.

I can recommend Kubuntu, KDE has better support for fractional scaling and is a very usable and distraction-free window manager. In general I'd try to stay away from NVIDIA drivers on Linux, unless you're doing GPU-intensive work the embedded graphics is often the better choice as it's less power-hungry as well and sufficient for most tasks.

And for KDE+Ubuntu it's always advisable to also check the official KDE distro KDE Neon, based on Ubuntu LTS. I don't know of the timeline for 20.04 based version though.

What's the advantage of Neon over Kubuntu?

This is a bug and is already fixed, debs can be installed by clicking. (Source: Alan Pope in the Ubuntu Podcast Chatter Telegram channel)

For the life of me I don't get how people always say upgrades are so easy on Ubuntu. They do? I just assume that I have to do a backup of my data, wipe the disk and install they new version. Ubuntu updates never worked for me.

I think it's one of the things Ubuntu dropped from the Debian experience. In-place upgrades are much less reliable. I also tend to wipe and reinstall on the desktop at least. Makes me keep configs in dotfiles/puppet and is good training for having to replace a computer. On the server side, upgrading between LTS releases seems to work better.

Ubuntu tests upgrades between LTS releases extensively and so do Ubuntu community developers and advanced users.

As you said, server users always upgrade. Enterprise desktop users upgrade. A lot of general users don't - they reinstall.

The upgrade process you should use with Ubuntu is different to Debian. In Debian you'd use apt, in Ubuntu you should use the update manager. Update manager specifically checks for upgradability, it has specific warnings and workarounds that are added for each release following testing and reports from end-users. This makes it much easier to upgrade.

The reason why users think the Ubuntu upgrade process is less reliable compared to Debian is they serve different user segments. Most Debian users are technically advanced, engage with the distribution and they often stay in their stream (e.g. testing). Ubuntu is used by lots of normal users - many may not pay particular attention to how packaging works - this means they often do things that make upgrades complex: install community PPA's that advance packages past the next LTS version, install Node into /usr by wiping out apts package knowledge, etc, etc. The range is just bigger.

For many normal users upgrading may no longer be the best option - it's just faster to reinstall. I personally do upgrades, I still find them magical and it's part of the fun: http://www.futurile.net/resources/ubuntu-upgrades/

Snaps also create a myriad on mount points which is quite annonying. I like Appimage though.

Tell me about it df -m was like myles long. And it [meaning snap] had separate auto-update procedures and janitorial daemons, which I had a hell of a time removing and disabling etc. I guess the best thing about snap is that you can uninstall all of them, I hope, and find the alternatives of the same features either in the main repositories or through every-lovable ppa. I loved 12.04 LTS, 14.04 LTS, even, but, this i…

I've disabled snapd and set it on hold so it's hopefully never installed again precisely because of this.
