Extremely short version:
Ubuntu 18.04 takes 1h 6min 17.410s to startup/ boot. It seems that systemd-tmpfiles-setup.service takes 59min 24.321s and apt-daily-upgrade.service 4min 13.257s.
More specifically, when I run a specific bash/python script with a lot of open() and close(), the next time I boot Ubuntu it takes that long.
Using $ sudo apt-get update , $ sudo apt-get upgrade and $ sudo apt-get dist-upgrade before I close the computer, sometimes lowers significantly the booting duration ( from 3 to 40 minutes). Additionally purging temporary files from the privacy settings (Ubuntu settings tab) doesn't work either.
Is there something I could do?
The checks I did :
$ systemd-analyze
Startup finished in 5.752s (kernel) + 1h 6min 11.657s (userspace) = 1h 6min 17.410s

Best Answer
There seems to be two main issues causing this delay to happen:
apparmorinterfering with permissions for some snap applications./tmpdirectory contains a very large number of files with mixed permissions.To solve this you need to work in two steps. The first step is troubleshooting and confirming the cause for this issue and the second step is solving it.
Troubleshooting:
First, you need to disable the apparmor service. To do this, please run the following command in the terminal:
Then, you need to clear your
/tmpdirectory. To do this, please run the following command in the terminal:If you get an error like
bash: /usr/bin/sudo: Argument list too long, this means your/tmpdirectory contains more files thanrmcan handle at once because the size of the command exceeds the shell'sARG_MAXfor Ubuntu ( 2MB ).To overcome this please run the following command instead in the terminal:
If you get errors during this operation like
No such file or directory., please ignore them as it is normal for files to be written and deleted constantly in the/tmpdirectory.Finally, please reboot your system and see if boot time improves.
Solving:
If the boot time improves after the troubleshooting step, then you have isolated the issue to snap applications permissions and you need to fix this by either giving these problematic snap applications more access permissions or even better removing them using
sudo snap remove APPLICATION_PACKAGE_NAMEand installing the same.debapplications from Ubuntu repositories usingsudo apt install APPLICATION_PACKAGE_NAME.After this you need to re-enable the apparmor service. To do this, please run the following command in the terminal:
Finally, please reboot your system and verify it is fixed.
