Gnudiff's questions

I am wondering, if this is something wrong with my installation, or should I report this to Ubuntu Redmine packagers.

I have an Ubuntu 20.04LTS system on which I installed redmine from Ubuntu distro:

apt install redmine redmine-pgsql

The installed version is redmine 4.0.6-2

The package works fine on its own, I can run redmine with mod_passenger.

However, whenever I try to install any plugin (from redmineUP, or other sources, checking for support for redmine 4.0), I:

1. get NO dependencies installed when executing bundle install --without development test --no-deployment -- just a message saying everything is fine.

2. get various missing dependancies related errors when execing bundle exec rake redmine:plugins NAME={plugin} RAILS_ENV=production

The only plugins work that are also packaged by distro: apt-get install redmine-plugin-custom-css works, but that is only a single plugin... about 2 are available, but no agile/kanban/etc.

As I started to dig in deeper, I noticed also that redmine is supposed to run under ruby2.6

However, Ubuntu releases don't have it: Ubuntu 18 used ruby2.3 and Ubuntu 20 uses ruby2.7 !

Has anyone been succcesful in using plugins with Ubuntu distro install of Redmine, or is this something I should report at Ubuntu distro?

I have a D-LINK DWM-157 USB 3G stick with working sms-only operator plan SIM card and without PIN code.

For some reason, neither gammu, nor gsmsendsms, nor gsmctl can connect to the device. They all report timeouts.

BUT wvdial finds the device allright and is able to both talk to it and make /etc/wvdial.conf entry:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CFUN=1,0
Modem Type = Analog Modem
; Phone = <Target Phone Number>
ISDN = 0
; Password = <Your Password>
New PPPD = yes
; Username = <Your Login Name>
Modem = /dev/ttyUSB0
Baud = 9600

I also can manually execute all AT commands and send myself an sms by echo > /dev/ttyUSB0

#cat < /dev/ttyUSB0 &
# echo "ATZ" > /dev/ttyUSB0
OK
# echo "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0" > /dev/ttyUSB0
OK
# echo "AT+CMGS=\"+myphonewithcountrycode\",145" > /dev/ttyUSB0
>
# echo "foobar^Z" > /dev/ttyUSB0
foobar
+CMGS: 2
OK
#

If I do a cat < /dev/ttyUSB0 & and then try gammu or gsmctl I can see that they both send AT commands and that modem replies with OK, but gammu/gsm act as if they didn't receive OK.

There is something very strangely wrong. What could be the problem?

There are various descriptions on the Internet on how to do that, but many of them seem to be outdated and some are contradictory; in some also the actual working part of solution (for me) was in comments, so I decided to share what worked for me.

Hopefully, if there are some changes, other people will be able to add other answers to keep it up to date.
