+===== Kept going to sleep =====
+After doing some upgrades, server Joshua kept going to sleep. I read this, and tried it:
+* https://unix.stackexchange.com/questions/529471/debian-10-adjust-sleep-settings-via-command-line
+//There is possibly a better way: edit /etc/systemd/sleep.conf and activate the following two lines://
+<code>
+AllowSuspend=no
+AllowHibernation=no

+===== Installed minidlna, a DLNA/UPNP Server =====
+Wanted to serve photos to the Oculus from the file system. So installed MiniDLNA, a.k.a. ReadyMedia.
+See https://www.bananatronics.org/installation-and-configuration-of-minidlna-readymedia/
+  sudo apt install minidlna
+  vi /etc/minidlna.conf (adjusting media_dir=/var/nas/Videos)
+  sudo service minidlna restart
+  sudo systemctl enable minidlna (not sure what this does)
+Visible from Windows Media Player, Oculus Pigasus, Oculus DeoVR
+===== Couldn't log in with SSH key =====
+Received this error in /var/log/auth.log
+<code text>
+ sshd[167454]: userauth_pubkey: signature algorithm ssh-rsa not in PubkeyAcceptedAlgorithms
+</code>
+Fixed by running these:
+<code bash>
+root@someserver~]# vim /etc/ssh/sshd_config
+// Add this to end of file
+PubkeyAcceptedKeyTypes +ssh-rsa
+root@someserver ~]# systemctl restart sshd
+</code>
+Reason? //This error occurs because the SHA RSA 1 algorithm that DeployHQ traditionally used for key generation, is no longer supported out the box in newer Linux systems.//

+====== Had problems when booting, apt upgrade'ing ======
+Ran this:
+<code>
+sudo apt full-upgrade
+</code>
+<code text>
+Errors were encountered while processing:
+ linux-image-6.1.0-13-amd64
+ linux-headers-6.1.0-13-amd64
+ linux-headers-amd64
+ linux-image-amd64
+E: Sub-process /usr/bin/dpkg returned an error code (1)
+</code>
+Trying this:
+<code>
+sudo apt remove aufs-dkms
+</code>
+====== Wouldn't Boot after fstab change ======
+I bought a large external HDD, modified fstab incorrectly. Kept getting errors on start up.
+It kept asking me for the root password for maintenance. Unfortunately I didn't supply the right one (see usual KeePass for the server name). That allowed me to edit the /etc/fstab value to look like this instead:
+<code bash>
+UUID=135260b9-26cd-41b9-8e69-9489a5d3fe32 /var/nas2     auto    rw,user 0       1
+</code>
+(I had left off the rw,user value, causing the 0 and 1 to be in the wrong positions. [5/6/2025])
