Even after removing Snap, Ubuntu still takes a lot of time to boot [duplicate]
Here is the log from systemd-analyze
Startup finished in 6.406s (firmware) + 4.794s (loader) + 4.066s (kernel) + 58.047s (userspace) = 1min 13.315s graphical.target reached after 56.065s in userspace

Can anyone please help me with that since even after removing snap and snapd I still face the issue of high boot time. Thanks in advance.
OS Name and Type: Ubuntu 20.04.2 LTS x64 My Laptop: HP 250 G7 Notebook PC Processor: Intel® Core™ i3-7020U CPU @ 2.30GHz × 4 Graphics: Mesa Intel® HD Graphics 620 (KBL GT2)
Solution 1:
There is no single magic improvement you can make to your apparently-properly-working Ubuntu system. (You already demonstrated that)
Sometimes there is a misbehaving service or flaky hardware, but your output does not show that.
You can make incremental improvements with better hardware (replacing HDD with faster SSD).
You can make an incremental improvement by testing your hardware for compatibility with hibernation (like the Windows FastBoot experience). Not all hardware is compatible with Linux hibernation, so it's disabled by default in Ubuntu. But it's trivial to enable. Of course, you can also just leave your system running (or sleep-to-RAM if portable), too.
You can make incremental improvements by reducing the complexity of your system. Your output shows a mixture of typical Server tasks (networkd, mysql) and typical Desktop tasks (NetworkManager, udisks2).
