Upgrade Ubuntu 18.04 LTS -->> 20.04 LTS

On hindsight this will probably go faster and more secured if I did a backup first and connected the laptop by cable not by wifi.

Asus laptop with ubuntu 18.04

First upgrade the packages.
$ sudo -i ## to get privilege of a root account
root@desktop # apt update && apt upgrade ## to update and upgrade packages to their latest


Second step is to install "update-manager-core"
root@desktop # apt install update-manager-core ## if you don't have it yet

Third step is to upgrade.
root@desktop # do-release-upgrade -d ## begin the upgrade, the "d" flag is to force the upgrade to the next new release

It took 90 minutes to download packages on my wifi speeds. I have a slow home wifi. There was some prompts here and there, primarily to ask me about packages being removed here and there. Answer with the first letter of your response and press enter. Configuration and installation took about another 60 minutes. The installation used the snap version of Gnome 3.34. It took some time too.

Fourth step is to reboot.

ZFS Unable to System Snapshot, bpool is Full?

I first encountered the problem after a routine update / upgrade of the system. Well there was a kernel upgrade and I have not checked how many old kernels are still left for backups in /boot. Apparently, there was a few and the partition is 85% full. Every software update included a warning because of the restriction in disk space. Also, zfs could not create snapshots. It is also full. This is not very clear to me. Snapshots were suppose to be diff copies so why would it take up a large space. Most of the snapshots are less than 2MB. Or 0MB. Another problem that popped up is the constant freezing of Rhythmbox. I don't know if the config files are corrupted. The CPU cycles from one to the next. Peaks for 5-6 seconds then on to the next CPU. This forced me to download Clementine and Audacious. But both applications do not find the zfs pool or don't show the zfs structure. Why not? My final solution is to reinstall Rhythmbox via snaps. I re-scanned the music libr

Renter's ID and Business Licensing 2023

Last year's business permit application involved an undertaking of submitting lessee list to the Barangay in order to get them ID's including one for the lessor himself. I received a letter of notification just before New Year's Day. It informed me that I might be denied renewal of permits because I did not comply with this undertaking. So the Renter's ID is a serious thing now. When I went ahead and applied for a business permit renewal at the local government office everything went well except they want my list of lessee. So I had to backtrack and go to the Barangay and submit the list. They produced the ID's and I provided the photo ID's and of course have it signed by the lessee. After that, they pointed me to the cashier to pay the taxes and permit fees which totaled php15,305.00 ($280.33) During the payment of Fire and Safety department, they reminded me to bring my fire extinguisher official receipts of payment. I can pick up my new pe
