startup - What service click-system-hooks.service in Ubuntu - Ask Ubuntu


trying speed system, have ubuntu 16.10, analyze system, checked services slow down, disconnected apt-daily.service automatic check new updates don't need.

please explain service responsible click-system-hooks.service , whether can deactivated.

$ systemd-analyze blame 26.630s apt-daily.service 17.067s click-system-hooks.service

sorry bad english, i'm ukraine, looking @ russian forums , not found answer use - click-system-hooks.service , possible disable it.

i wondered may on ubuntu installation, had @ service file /lib/systemd/system/click-system-hooks.service:

[unit] description=run click system-level hooks documentation=man:click(1)  [service] type=oneshot remainafterexit=yes execstart=/usr/bin/click hook run-system restart=no  [install] wantedby=multi-user.target

so, responsible invoking /usr/bin/click hook run-system. according man-page, click

package management tool ubuntu touch

and parameters hook run-system mean

run system-level hooks installed click packages. useful when starting images preinstalled packages may not have had system-level hooks run when building image.

concluding, if don't run ubuntu touch, may disable service via sudo systemctl disable click-system-hooks.service or remove click system.

for me, suspect, came package unity8-desktop-session indirectly depends on click , must not installed without.
