Anacron question

[Frederic Muller]

Hi!

Following up on a old question of mine about daily backup tools I did 
follow the advice and am using borg successfully. So thank you for that: 
very easy to setup and works great.


However wanting to do that daily automatically from my laptop to a local 
network drive I looked for a way to start the backup like 10 minutes 
after I switched on the PC and only once a day which led me to anacron.


Installed it, set up the anacron job and the problems arrived. Initially 
tried to run it as my user but that didn't work.


@daily  10  daily-backup    su fred -c "/home/fred/dao2/tech/daily.sh"

Simplified the command to run as root but that also didn't work. It 
seems anacron doesn't run.


@daily  10  daily-backup    /home/fred/dao2/tech/daily.sh


Finally found one or two post saying you can add a cron job that runs 
hourly and launch the anacron tasks.


I have this in my user crontab:

@hourly /usr/sbin/anacron -s -t $HOME/.anacron/etc/anacrontab -S 
$HOME/.anacron/spool


This unfortunately get the task run randomly and definitely not once per 
day. I sometimes get it to run 3 or 4 times in the same day while 
sometimes I feel it's does not run and so I run it manually.


So my question is how do I get anacron "fixed" and running once daily?

Thank you.

Fred

Anacron probably isn't the right tool for this, since you don't want to
run the backup at a fixed time but "10 minutes after I switch on the PC
and only once per day". Unless you always switch on the PC at the same
time, you may be better triggering the job at boot time. You can
trigger something at boot by using the "@reboot" keyword (crontab(5)).
You'll want to run a script that a) checks if backup has already run,
and b) waits 10 minutes before running it. You can check if it has run
by adding a hook to your backup script that just logs the last time it
finished successfully.

BTW, I recommend using borgmatic for regular borg runs, but you still
have to take care of the timing yourself.

Re: Updating failed midway. System will not boot.

[murph nj]

I got it running.  The write-up will not be super complete, but here goes.

When I checked for kernels, I saw that there was a new one available
(6.9.9?)  That installed OK, and seemed to resolve the uname-r issue.

Another package (ko-something) that was part of the plamsa desktop was
causing a problem.  I removed plasma desktop, and was able to
continue.   (I've since re-installed, and KDE is working)

It seems I only see one small problem at this point.
libvt-daemon is 4.1.0-1.fc28 (!) so I suspect that this may have been
quietly lurking for a while.
It will not uninstall, even if I have a newer one installed and
updated.  I've double-checked, and removed the last remaining VM on
this machine, no longer an issue.

I am able to boot fully now, as multi-user, as well as graphical.  I
think that with this mess, between the hardware failure, and the
disaster, and subsequent recovery, I may just move all of my work off
of this machine, and onto a newer one, and finally semi-retire this
laptop.

You may (probably?) be able to cleanup that F28 package by following
the post-upgrades steps at
.
There's also a section on Resolving post-upgrade issues.

How about a systemd timer that is fired fired 10 minutes after boot. 
Its ExecStart could call a script that checks for a touched file ( a 
semaphore ).  If the semaphore is not from today it would call the 
backup program.  On successful completion it would refresh the semaphore.

no sound on bluetooth headphones

[Geoffrey Leach]

Using bluetooth on Fedora 40/xcfe4 for the first time

Headphone pair OK
Bluetooth is active and running
Bluetooth Manager sees headphones
Volume Control  does not see the headphones

Testing with mplayer foo.mp3; sound at speakers

I'm assuming that there is some critical enabling that needs to happen.
Suggestions?

Thanks

Essentially what I said, but I think a crontab "@reboot" line is easier
to set up.

I hear you. Now I went the anacron direction as the man page just says that:

"Description

Anacron is used to execute commands periodically, with a **frequency 
specified in days**. Unlike cron(8), it does not assume that the machine 
is running continuously. Hence, it can be used on machines that aren't 
running 24 hours a day, to control regular jobs as daily, weekly, and 
monthly jobs.


Anacron reads a list of jobs from a configuration file, /etc/anacrontab 
(see anacrontab(5)). This file contains the list of jobs that Anacron 
controls. Each job entry specifies a period in days, **a delay in 
minutes**, a unique job identifier, and a shell command.


For each job, Anacron **checks whether this job has been executed** in 
the last n days, where n is the period specified for that job. If not, 
Anacron runs the job's shell command, after waiting for the number of 
minutes specified as the delay parameter. "


So it runs daily, allow for a delay when starting and supposidely checks 
whether the job has been executed... seems like what I was looking for no?


And arguably modifying my backup script to check if it ran today already 
and then run it if not will probably be faster than troubleshooting 
anacron at this point. ;-)


Thank you.

@Mike I also read that on systemd distro cron and anacron are things of 
the past and we should be looking at systemd timers... so thank you for 
that.


Fred
