Hi,

Gunnar ( Gunnar Gervin <[email protected]> ) is having problem with
his laptop.
The system crashes post-update.
He need to do clean install every time.
And this is probably time consuming for him.
If other user has some hints...
[...] three times run a "sudo sync" [...]
While I've read about issuing sync *twice* with the explanation
that sysadmins are a supersticious bunch [1], the sudo is most
definitely unnecessary.
I think the running twice is also a bit of a too much extra.
I'm really asking why do it 3 time.
In case it came back to the prompt *before* finishing to do it's job ?

Misunderstanding: I wanted to suggest to run a "sudo sync" (1) before
and (2) after the update and (3) before the system shutdown, in order to
exclude that data wasn't fully written to disk at possible critical
moments. This in total are three different situations when I suggest to
run the sync command, and in all this three different situations it
shall be run, thus running it three times (in total three times, not
triple repeated in one of the situations).
By the way, running it as "sudo" is not harming and makes sure that
everything is written to disk without having to know if the sync command
would behave different with and without the sudo. The point is, you want
to debug a situation, you want to find out why an update is failing so
severely and not reported to fail like this elsewhere, and sudo will not
harm for this purpose while not using sudo could have left doubts if
really all is written to disk - pragmatically focusing on problem
solving without maybe producing more problems and without loosing time
to construct a most elegant version of problem solving. Just get the
problem solved!
I am curious to read if the "sudo sync" runs solved the update problem.
Good Luck! Marco.
