Change Fedora Silverblue automatic updates to check

Set the AutomaticUpdatePolicy to check in /etc/rpm-ostreed.conf:


[Daemon]

AutomaticUpdatePolicy=check


Then reload the service:


sudo rpm-ostree reload


Enable the timer if not already active:


sudo systemctl enable rpm-ostreed-automatic.timer --now


This configures the system to check for updates automatically and display them in rpm-ostree status, but does not download or apply them.  You’ll see notifications about available updates, including CVEs, without any automatic downloading.

Dearpygui resizable table

Fixing DNS Resolution problems with Linux Mint 19

Fixing DNS Resolution problems with Linux Mint 19 Linux Mint 19 has an issue (at least on the machines I've installed it on) where resolv.conf has its nameserver entry pointing to 127.0.0.53. That works fine except for resolving local subnet names (in my case 196.168.1.x). The following fixes the symptoms, though I still don't know why 127.0.0.53 is being used instead of the assignment from DHCP. Run in root console, or sudo: # apt install resolvconf # nano /etc/resolvconf/resolv.conf.d/tail nameserver 192.168.1.1 # resolvconf -u This will tag the local nameserver entry onto the end of resolv.conf and persists through resets.
