Raspbian: can't start tango-db service due to Debian bug

General Installation
1

Hi all,

I am using tango 9.2.5 on a Raspberry Pi 4, and there is a problem starting the tango database service at boot.

At first, it works fine, but after a while the service doesn’t start at boot any more. To make it work I have to restart the service everytime by:

$ sudo /etc/init.d/tango-db restart

Then after a while, it is very hard to restart the server this way.
The output of

$ sudo /etc/init.d/tango-db status

is below.

pi@raspberry:~ $ sudo /etc/init.d/tango-db restart
[ ok ] Restarting tango-db (via systemctl): tango-db.service.
pi@raspberry:~ $ sudo /etc/init.d/tango-db status
● tango-db.service - LSB: Start the tango control system database daemon
   Loaded: loaded (/etc/init.d/tango-db; generated)
   Active: active (exited) since Sat 2021-02-13 11:32:40 GMT; 16h ago
     Docs: man:systemd-sysv-generator(8)
  Process: 1523 ExecStart=/etc/init.d/tango-db start (code=exited, status=0/SUCCESS)

After some searching, I found that this is due to a bug of Debian as reported here

I am not sure how to patch/fix this. I wouldn’t want to install a higher version of tango until an installation package for Raspberry Pi is available.

Anyone experiencing the same and has some solution?

It might be easiest to apply the patch from the bug report, see Fix Bug#906921 (!1) · Merge requests · Debian Science Team / tango · GitLab yourself.

Which exact tango package version are you using?

Thanks. I am using tango-db 9.2.5a+dfsg1-2+b2
Will try the patch now.

Do you know if that tango package is straight from debian? If yes, I know who to ping for an updated package, as 9.3.4 came out recently.

Yes, I install from the Debian repo (apt-get). But maybe it’s MY BAD. I didn’t install tango-starter from the beginning. I have installed and the problem seems to have gone. If it comes back I will apply the patch.

On 9.3.4 I have a couple of months till production and I hope that it would be available on the official Debian repo.

Thanks!

It happens again, so I am gonna apply the patch. I understand that to apply the patch is to simply replace line 6 & 7 of the tango-starter file located in /etc/init.d/ from:

# Should-Start:      tango-db
# Should-Stop:       tango-db

to

# Should-Start:      tango-db network
# Should-Stop:       tango-db network

Still doesn’t work when there is no network (internet) connection at boot. Does anyone know how to correctly apply the patch?
Thanks!
