NMGLugers, I have been updating both Debian and Xubuntu. On Debian I did the upgrade from Stretch to Buster. I encountered a program called 'minissdp' as part of the upgrade and had a few issues with it. It is designed to allow network awareness of Upnp, so it requires setting permissions to open a port for gathering data. I left it unconfigured during the upgrade, as this was allowed, but subsequent updating flagged it as partially installed. I finally removed it. With Buster running all other routine things I do seem to work, though I have not been using it long enough to rule out all problems. Updating now brings up warnings that the trusted gpg signatures do not match, so I will re-visit this issue which I had resolved in Stretch. I will be trying to sort out whether minissdp is needed or not and what to do to configure my apt files to correct the error messages about the trusted.gpg. I will have to research this and try to remember what I may have done to the keys involved. With Xubuntu I am using both 18.04 and 20.04 on different hardware. My thoughts on this are that I should try the six month release cycle, but my gut says I prefer the stability of fewer glitches and more gradual changes in the two year release cycle. The six month cycle gives newer kernel updates that bring the newest modules and controls. This has alerted me to learning more about systemd which is the control mechanism for the on the fly kernel adjustment and system administration. It also dawned on me that 'mount' no longer lists just the mounted devices, but lists the several mounted cgroups as well. If one needs to know hardware it is better to use 'lsblk' instead. And 'df -H' to see how much space is available on your drives. Systemd and control groups are new to me, so I will be reading the manual and looking at the tutorials to find out more as I go along. With the Xubuntu I will be trying to learn and catch up to the control group system, but I think I will settle with the LTS two-year cycle for updates as a rule and use a usb-installed system to see what the new, six month, release is doing. Where I tutor newcomers I will definitely favor the LTS version. We have a virtual meeting on July 2, at 5:30 pm, MDT. I will comment more on these issues and attend in Xubuntu 20.04 to see how that works. I do not anticipate any issues with the connection. We are still meeting virtually as noted on our website. Thank you, Ted P.
