RC 64 Volla

[RayCulp]

@domubpkm Thank you, but I'm confused. Does this mean that cron is indeed available on UT 20.04?

In any case, I asked about cron in one of the Telegram groups just now, and the recommendation I received was to use systemd timers instead of cron jobs. I hope this helps!

@domubpkm Between ota 25 (xenial) and the RC release there could be many differences ... I will try to adapt call-recorder to Focal OTA-2 Stable, but no promises.

[domubpkm]

@Br1 The callrecorder should work for OTA-25. If there is an OTA-26 that fixes boot issues (last 3 RCs), no. Is not it ?

Edit : I did : anyway, OTA-25 is no longer installable, the dev channel is installed instead (system parameters). So no more callrecorder.

Edit 2 april 18 : i installed dev 1111 (2023-04-18/2) and callrecorder v 1.01 works ! I stay here until a focal that suits me.

I just hope your work is progressing as you wish, because all of your scripts are great and will enhance focal environment (as they do for xenial).

I installed it yesterday, seems to work fine ... a few days of testing

---- UPDATE OTA-2 Focal ----
---- Stable Channel ----

Usual three steps :

1 - download callrecorder-ota.2.tar.gz from here : www.spacelinux.it/UTouch/callrecorder-ota.2.tar.gz

2 - open file manager, go to Downloads tap callrecorder-ota.2.tar.gz and tap extract archive

3 - open terminal, type :

sudo Downloads/callrecorder-ota.2/callrec-install

and hit enter,

type 1 + enter to install

type 2 + enter to uninstall

and reboot.

---

As in previous versions, install script asks you how many days you want to keep recorded calls, hit enter for default (30 days) if you later decide to change, repeat the installation (in this case reboot not required).

Focal required several changes, callrecorder now is a systemd service, to delete older calls there is a systemd user timer .

preview of callrecorder service :

[Unit]
Description=Call Recorder

[Service]
Type=simple
ExecStart=/home/phablet/.callrec/prepare-sh
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

systemd user timer requires 2 files, rec-remove.timer :

[Unit]
Description=Run every day at 11:00

[Timer]
OnCalendar=*-*-* 11:00
Persistent=true

[Install]
WantedBy=default.target

and rec-remove.service :

[Unit]
Description=Remove older calls

[Service]
Type=simple
ExecStart=/home/phablet/.callrec/rec-remove-sh

[Install]
WantedBy=default.target

to run daily the script rec-remove-sh :

#!/bin/bash
#
days=+30
# delete recordings (except saved directory) older than ... days
find /home/phablet/MyRec -type f -not -path '*/saved/*' -mtime $days -exec rm {} \; 2> /dev/null ;

. small change, now you can save recorded calls in "saved" folder and will not be deleted

. small differences in other scripts (new paths)

. as for previous versions callrecorder must be uninstalled before proceeding to ota update.

@Br1 I don't know if it is just me, but the download link does not seem to work, I get a Not Found error.

[Br1]

@ATTESA try direct link : www.spacelinux.it/UTouch/callrecorder-ota.2.tar.gz

@Br1 Hallo, thanx a lot for your work, but :
:~/sudo Downloads/callrecorder-ota.2/callrec-install

:~/sudo: callrec-install:command not found

[Br1]

@dosolly
On a hunch I did it again and works ... you have extracted it ?

in Downloads directory there should be "callrecorder-ota.2" subdirectory that also contains "callrec-install"

[dosolly]

@Br1 Thanks for your help, at least the installation worked. Now I have to test it extensively.

[dosolly]

@Br1 OK, thx a lot, works now like a charm.

[domubpkm]

@Br1 Hello. Is your OTA-2 work / procedure the same for OTA-3 ? Thanks again

[Br1]

@domubpkm no ota 3 update for my device, i cannot test it
yesterday I ordered a google pixel 3a xl ... it will take some time.

Don't really understand. Your current phone is broken / out or the OTA-3 update will come later even if you ordered a new phone ?

[Br1]

@domubpkm from what I understand ota 3 update will be available only for currently supported devices
Xiaomi MI A2 isn't there, it doesn't have a maintainer

[domubpkm]

@Br1 Okay, and unfortunately for you. I didn't understand why you got OTA-2 and not OTA-3. I will wait for a future feedback about the DNS change on OTA-3, because your procedure has become essential to me, more than VPN on UT ultimately.

OTA 3 Stable channel --- You can reinstall, no changes are necessary.
