cjones's questions

I use a combination of Timeshift and Cronopete for backups. My desktop has some internal HDDs that are used for doing backups. The system is on a separate NVMe.

I was able to get this working for Timeshift, but Cronopete expects there to be USB storage as the backup media. If you try to "Store backups in a folder", which seems is how'd I'd pick these internal HDDs as the backup destination, you get this message:

Reading the following link, it sounds like I need to install dconf Editor and toggle enable-folder-backend to on:

https://ubuntuhandbook.org/index.php/2018/07/cronopete-time-machine-like-backup-tool/

However, when I navigate there, enable-folder-backend does not appear as an option:

I'm using the "Ubuntu focal 64-bit" installer located here:

Suggestions for how to enable this?

I seem to recall this working OOTB with VMware Player, but it has been a while and I could be mistaken. Using kvm2 for minikube, never used for other VMs, but want avoid having two hypervisors.

At any rate:

• Guest IP: 192.168.122.197
• Host IP: 10.0.0.165
• Web App IP (minikube ip): 192.168.39.128

I've installed the latest VirtIO drivers.

The guest can ping 10.0.0.165, but the host cannot ping 192.168.122.197. The guest cannot ping 192.168.39.128 as it comes back with Destination port unreachable.

This is the xml for the network adapter for the VM:

<interface type="network">
  <mac address="52:54:00:d9:97:d0"/>
  <source network="default" portid="30b67932-cf43-419b-bd26-5a07f451078e" bridge="virbr0"/>
  <target dev="vnet0"/>
  <model type="virtio"/>
  <alias name="net0"/>
  <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/>
</interface>

When I try to access the web app from a browser in the guest, it is unable to connect: Hmmmm... can't reach this page... took too long to respond.

What should I be doing to get this working?

Perhaps there is a better way of doing this, but I'm trying to access the web app running in the VM (VMware Player 16) from the host's Chrome browser.

• The host is Windows 10 and the VM is Ubuntu.
• I have a web app running in the Ubuntu VM at 192.168.39.113:80 (minikube VM inside of kvm2).
• The VM is using a bridged connection and has an IP of 10.0.0.205.
• I installed SSH on the Ubuntu VM with sudo apt install openssh-server.
• I can SSH into the VM from the host now.
• I'm trying to create a tunnel with ssh -L 8080:192.168.39.113:80 [email protected], but I'm still unable to to connect to the web app from the host's browser when I go to 10.0.0.205:8080.
• I did enable AllowTcpForwarding yes followed by sudo service sshd restart, which still I'm not able to connect to the web app from the hosts browser when I go to 10.0.0.205:8080.

Suggestions for how to resolve this?

Basically, follow the steps as outlined here: https://wiki.postgresql.org/wiki/Apt.

1. sudo apt-get install curl ca-certificates gnupg
2. curl https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
3. sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
4. sudo apt-get update
5. sudo apt-get install pgadmin4

(The actual command for the last step includes postgresql-11. I never do that because I just want pgadmin4 and have never had issues with it working properly.)

Anyway, this is what happens when trying to install:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package pgadmin4 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'pgadmin4' has no installation candidate

I've redone the steps with the same result.

I did also try to do the following, but it requires python3.7 which I'm not going to install.

sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt eoan-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

Verified focal shows up at apt.postgresql.org:

Kind of stumped after that as to what to do.

Suggestions?

Only been using Ubuntu for a couple weeks.

The amount of wasted space along the top of some windows is almost comical, but I realize that is largely due to the developers. For example, Chrome and Microsoft Teams make great use of the space. Firefox and Visual Studio Code... oof.

Trying to resolve this, I came across an answer on here suggesting gnome-shell-extension-pixelsaver. Worked great for several days. Then just quit working yesterday. I've tried to sudo apt purge gnome-shell-extension-pixelsaver and then reinstall. Restart, etc. Doesn't fix it.

I also tried no-title-bar and also made sure x11-utils was installed. Doesn't do anything either.

I haven't made any changes to the system, so I'm perplexed why it would just quit working.

Any suggestions on how to resolve this?

EDIT - 3/27/20

I ended up doing a reformat for a couple reasons, this being one of them.

Used this extension on the clean reformat:

https://github.com/pixel-saver/pixel-saver

Again... works for a few days and then stops working. Reinstalling it does nothing.

Basically, I'm trying to reduce the thermals of an Ubuntu install and trying everything. Quiet as can be in Windows 10 except for gaming, as it should be; Ubuntu fans rev up to 75-100% doing simple tasks.

Anyway, going down the list of things to try and PowerTOP is one of them.

Ran sudo powertop --calibrate --html enough times to have enough measurements for doing --auto-tune. Was getting errors related to there not being enough measurements.

Now when I run sudo powertop --auto-tune I just get the following output. Isn't clear to me if it is working, but seem like it isn't:

modprobe cpufreq_stats failedLoaded 435 prior measurements
RAPL device for cpu 0
RAPL Using PowerCap Sysfs : Domain Mask f
RAPL device for cpu 0
RAPL Using PowerCap Sysfs : Domain Mask f
Devfreq not enabled
glob returned GLOB_ABORTED
Leaving PowerTOP

So what gives here? Googling isn't helping much.

Otherwise, I've tried tlp and a few other things. Only marginally help in reducing fan noise.
