Ubuntu 19.10 не может найти пакеты libnm-glib, libnm-glib-vpn и libnm-util

Я пытался создать плагин сетевого менеджера для Ubuntu 19.10, но autogen.sh не работает из-за следующей ошибки

checking for LIBNM_GLIB... no
configure: error: Package requirements (NetworkManager >= 1.2.0
    libnm-util >= 1.2.0
    libnm-glib >= 1.2.0
    libnm-glib-vpn >= 1.2.0) were not met:

No package 'NetworkManager' found
No package 'libnm-util' found
No package 'libnm-glib' found
No package 'libnm-glib-vpn' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBNM_GLIB_CFLAGS
and LIBNM_GLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

версия openconnect должна быть в порядке

OpenConnect version v8.02-1build1
Using GnuTLS. Features present: TPMv2, PKCS#11, RSA software token, HOTP software token, TOTP software token, Yubikey OATH, System keys, DTLS, ESP
Supported protocols: anyconnect (default), nc, gp

При попытке установить недостающие пакеты кажется, что они были удалены / заменены

sudo apt install libnm-util-dev libnm-glib-dev libnm-glib-vpn-dev
