Comment 275 for bug 1810183

if anyone have a problem with oserror, as advice by Håkon Vågsether (haakov) check 1 sec wait solution, another way that worked for me, i have edit .service before start the install and changed the line 7 from Type=simple to Type=idle, in fact man define:

Behavior of idle is very similar to simple; however, actual execution of the service program is delayed until all active jobs are dispatched. This may be used to avoid interleaving of output of shell services with the status output on the console. Note that this type is useful only to improve console output, it is not useful as a general unit ordering tool, and the effect of this service type is subject to a 5s timeout, after which the service program is invoked anyway.
