Добрый день!

В системе может быть установлено несколько пакетов kernel-headers* точно так же, как и остальных пакетов ядра. Но в таком случае update-kernel не может обновить ядро:

# update-kernel -f

Package kernel-headers-elbrus-def is a virtual package provided by:
  kernel-headers-elbrus-def#4.9.146-alt2.7.7 4.9.146-alt2.7.7 [Installed]
  kernel-headers-elbrus-def#4.9.170-alt3.8.2 4.9.170-alt3.8.2
You should explicitly select one to install.
E: Package kernel-headers-elbrus-def is a virtual package with multiple good providers.

Явное указание версии ядра посредством -r 4.9.170-alt3.8.2 не помогает.

Проблема вылезла на e2k и на версии update-kernel-0.9.13, но:
1) в имзменениях 0.9.14 я ничего по данной проблеме не вижу;
2) 0.9.13 на e2k такой же, как в Сизифе;
3) по идее, ничего архитектурно-специфичного в данной проблеме нет.
