+For OpenSuse repositories it might be required to delete, redownload and reinsert the keys similar to the following examples:
+<code>
+sudo rm /usr/share/keyrings/obs-onedrive.gpg
+sudo apt-key --keyring /etc/apt/trusted.gpg del 876D807E
+wget -nv https://download.opensuse.org/repositories/home:npreining:/debian-ubuntu-onedrive/xUbuntu_22.04/Release.key -O Release.key
+sudo apt-key add - < Release.key
+sudo apt-key export 876D807E | sudo gpg --dearmour -o /etc/apt/trusted.gpg.d/onedrive.gpg
+sudo apt-key --keyring /etc/apt/trusted.gpg del 876D807E
+sudo vi /etc/apt/sources.list.d/onedrive.list

+===== not configured yet =====
+In case of dpkg dependency errors of a package that isn't configured yet, trigger configuration manually.
+Example error:
+<code>
+ dpkg: dependency problems prevent processing triggers for libglib2.0-0:i386:
+ libglib2.0-0:i386 depends on libc6 (>= 2.28); however:
+  Package libc6:i386 is not configured yet.
+</code>
+<code>
+sudo dpkg --configure -a
+</code>
+===== apt-key deprecated =====
+Apt Error: "Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8))."
+Find the repository causing the error. Note that the apt-key output does not contain the url but descriptions and it might be difficult to find the relevant entry.
+<code>
+sudo apt-key list | grep -B 2 -i something
+</code>
+Once the entry is found, use the last 2 blocks of 4 characters of the key id to export it and then create a separate gpg file fir it:
+<code>
+sudo apt-key export 12345678 | sudo gpg --dearmour -o /etc/apt/trusted.gpg.d/name-of-file.gpg
+</code>
+Finally, the old key id can be removed from the trusted.gpg file:
+<code>
+sudo apt-key --keyring /etc/apt/trusted.gpg del 12345678
+</code>

+===== apt fastest mirror =====
+apt-get now supports a 'mirror' method that will automatically select a good mirror based on your location. Adding the following at the top of ''/etc/apt/sources.list'' file will pick the best mirror:
+Follow this with:
+<code>vi /etc/apt/sources.list</code>
+Adjust for the appropriate ubuntu distribution.
+<code>
+deb mirror://mirrors.ubuntu.com/mirrors.txt focal main restricted universe multiverse
+deb mirror://mirrors.ubuntu.com/mirrors.txt focal-updates main restricted universe multiverse
+deb mirror://mirrors.ubuntu.com/mirrors.txt focal-backports main restricted universe multiverse
+deb mirror://mirrors.ubuntu.com/mirrors.txt focal-security main restricted universe multiverse
+</code>
+Do an update for apt to get/select the best mirror before any installs:
+<code>apt-get update</code>
