I have fs.inotify.max_user_watches=524288 in cat /etc/sysctl.confcat
And still, every distro updrade, and "now-and-then" I have to do "sudo sysctl -p "
- why is it not persistently saved ? and reduced to 64k now and then?
I tried Audacity as there are instructions and it worked in the past. But ALSA is no longer an option. (that was requires by the instructions) I see "pulseaudio, pipewire and default" as recording devices, but nothing that seems to output audio.
I have installed "beyond compare" from scooter software.
now, on apt update I get:

The issue is that I cannot see that source among my sources in the "Software & Updates" (GUI) - nor is it visible in /etc/apt/sources.list
So - this makes me think: what other PPA's may I have that I am not aware of? - this does not seem to be very wise/safe. I get it - I did install the software, but still, I'd expect the added source to be visible among PPA's ? - or am I missing something?
New software has been introduced on Ubuntu 23.10: a new Flutter-based App Center and a Firmware Updater tool, as can be read in Ubuntu Desktop 23.10: Mantic Minotaur deep dive.
However, after upgrading from Ubuntu 23.04 to 23.10, I can't find either of these tools.
How can I get them?
(Ubuntu) computer has two network interfaces: (and is not sunning iptables)
wlx1cbfce8bd2bd: inet 10.1.1.129 netmask 255.255.255.0
on this network, there is a device: 10.1.1.10 - with a UDP port 10000 that I wish to publish to the internet.
the second interface is....
enp4s0: inet 192.168.1.80 netmask 255.255.255.0 (this is connected to Fortigate Firewall)
Fortigate LAN IP is: 192.168.1.1
I wish to enable somebody to connect to the UDP port 10000 of the 10.1.1.10 device from the internet.
I do know how to set up NAT(Virtual IP) and IP4Policy to forward traffic to 192.168.1.80 - but I do not know how to do it to 10.1.1.10
I assume I need route(s) on Fortigate, as well as on my PC (192.168.1.80) to achieve that.
I have no problem NATting from the firewall to the PC's 192.168.1.80 address and some port, but how should this traffic be forwarded to the 10.1.1.x network?
To reproduce. install anbox snap install --devmode --edge anbox
In my case, I installed on a fresh installed Ubuntu 21.10
Then I discovered that the binder module was not working as expected. Anbox devs could not figure this out: https://github.com/anbox/anbox/issues/1949
Please advise.
My laptop's SSD has been moved from an older to newer model (E6530) - And Ubuntu upgraded for years. The situation is that the Nouveau driver does not display anything on HDMI out, but the HDMI device is showing just fine is "displays" Nvidia driver works as expected. (so hardware is ok)
- How can I make the Noveau driver "good as new" ? (forget any and all of it's config over time)
The system is recently upgraded to 21.10 Every boot starts with this simple text message. I need to enter the LUKS passphrase. Once done .. it boots as before, and with the nice GUI, asks again for the LUKS passphrase.
This issue appaered after using a grub tool to update grub with new kernel, because after the 20.10 upgrade, I still had grub with a kernel from 19.xx or so kernel.
Please help me restore "normal" boot - straight to graphic LUKS passphrase question.
Right after upgrading a Ubuntu 21.04 to 21.10, I got this issue: Chromium/Firefox won't start. The error(seen in terminal) is:
$ firefox
cannot attach cgroup program: Operation not permitted
Regardless of my Nvidia card is in performance mode or on-demand mode (PRIME profiles) - the HDMI does not work - except during boot, and until the login screen.(Login display makes it disappear)
FWIW: this laptop and HDMI worked fine with Ubuntu 20.10 - HDMI was detected on plugin. I am using nvidia-driver-390 ubuntu/gnome makes no difference. I am unable to select "ubuntu on xorg" when using nvidia Drivers (and intel does apparently not support the HDMI out)
Nautilus can't copy between SMB and MTP device. same for rsync which gives:
rsync: [receiver] mkstemp "/run/user/1000/gvfs/smb-share:server=192.168.1.20,share=backup/phone/files/filename.txt" failed: Operation not supported (95)
All I am trying to do is a phone file backup, but smb or mtp implementation is apparently not compatible..
Dell T420 sever; BCM5720 interfaces are gone after upgrade from 19.10 ifconfig lists only "lo" and "tun0"
/etc/netword/interfaces show "auto lo em1" and "iface em1 inet static" ... (with settings)
lspci proves that the ethernet adapters are there, how can I make them be used by Ubuntu 20.04 (server)
Dell Latitude E5520.
Fn+F5 always shows a "disabled touchpad" symbol, but it remains active.
There is a long time where SSD does nothing.
- How can I find the fault and fix it ?

I have a binary that outputs to a terminal window when running. I wish to start this binary from a shell script, because I need to set a environment variable first.
But, when it's executed from:
#!/bin/bash
export THIS=set
./binary
I can no longer see the binary's output to terminal... How can I get the output while executing with a script?
After upgrading to 15.04 , one computer is very, very slow to boot -several minutes, instead of ~20sec.

Proprietary drivers 331.89 do not give me OpenCL. (tried both tested/updates) for a while I had version 304.123 that worked - except I wanted the current drivers, and now are unable to downgrade.
Anyway - I could downgrade by workaround, but I wish 331.89 worked.
I used "darktable -d opencl" as test alos added symbolic link to darktable, but that does not help with 331.89
I have a 14.10 server with OpenVPN 2.3.x How to configure it for IPv6 ? (I have a natted IPv4 that cannot be port forwarded.) I wish to be able to receieve VPN connecions from Android OpenVPN client.
This guide would be great, https://help.ubuntu.com/14.04/serverguide/openvpn.html if there was a IPv6 version :)
I used L2TP IPsec VPN Manager until upgrading to 13.10
It worked previously. But now it does not work.
The ipsec server (Fortigate firewall, logs everything as just fine, then says the client disconnected.)
The line IPCP terminated by peer (Unauthorized remote IP address) - makes no sense, the IP is provided by the FW, and is from the right pool.
Also, FW does not log any problem.
Finally: connecting to the same FW using Android - works fine.

So how to connect to ipsec VPN ?
If Nautilus is used to drop a file on a samba share into an app, then the app will see: "SMB://server/share/file"
How is the app supposed to detect real, working gvfs path of that file ? different Ubuntu versions have different paths to the gvfs folder.
is there an API, or conversion script, or anything like that, that could translate that into the ull GVFS path ?
