I feel that MyPyClass gets created with arg file=".../mytonctrl/" at some places, and gets created with with arg file=".../mytoncore/" at some other places, and https://github.com/igroman787/mypylib/blob/e194d7e8e3151549f56419d6377c16cb1e2f2e8f/mypylib.py#L306 MyPyClass::GetMyFullName returns wrong value.

I launch mytonctrl under root.

The .db file exists at /usr/local/bin/mytonctrl/mytonctrl.db and the mytonctrl command indirectly (via MyPyClass::dbLoad https://github.com/igroman787/mypylib/blob/e194d7e8e3151549f56419d6377c16cb1e2f2e8f/mypylib.py#L531 ) tries to read /usr/local/bin/mytoncore/mytoncore.db where it doesn't exist.

UPDATE: After many rounds of rm of a lot of things and after many reinstalls with edited .py files and installers scripts files, this is no longer the case, see the following comment.

[asmexcaliburwoods]

One workaround is:

sudo cp -v /usr/local/bin/mytoncore/mytoncore.db /usr/local/bin/mytonctrl/mytonctrl.db

You can also verify that you have a correctly initialized mytoncore db:

sudo cat /usr/local/bin/mytoncore/mytoncore.db

Its output should be like:

{
    "config": {
        "logLevel": "debug",
        "isLocaldbSaving": true
    },
    "fift": {
        "appPath": "/usr/bin/ton/crypto/fift",
        "libsPath": "/usr/src/ton/crypto/fift/lib",
        "smartcontsPath": "/usr/src/ton/crypto/smartcont"
    },
    "liteClient": {
        "appPath": "/usr/bin/ton/lite-client/lite-client",
        "configPath": "/usr/bin/ton/global.config.json"
    },
    "miner": {
        "appPath": "/usr/bin/ton/crypto/pow-miner"
    },
    "sendTelemetry": false
}

Problem No such file or directory: '/usr/local/bin/mytoncore/mytoncore.db' may pop up due to the fact that the program is running under a different user. For example, it was installed by the superuser. Then the configuration file will be located here: /usr/local/bin/mytoncore/mytoncore.db. And when run as a user, the configuration file will be expected here: /home/{user}/.local/share/mytoncore/mytoncore.db

Another warning message No such file or directory: '/usr/local/bin/mytonctrl/mytonctrl.db may appear when you first start the program - this is normal
