A atualização de usbmuxd soluciona o problema. Eu baixei um novo pacote do link (1.1.1 ~ git20180428.b95a0a0-1) e o instalei. Surpreendentemente, era compatível com o Ubuntu 18.04.
Eu tenho um iPhone 8 que inicialmente se conecta via USB para que as pastas Imagens e Documentos estejam disponíveis no Ubuntu 17.10. No entanto isso funciona apenas uma vez entre o Ubuntu é reiniciado.
Como faço para solucionar isso?
Isso deve ser um bug ou um problema de configuração, não algum software ausente ou completamente desativado, porque ele realmente funciona na primeira vez após a reinicialização.
O que acontece é que, se eu desconectar e conectar o iPhone novamente, a pasta Imagens não reaparece no aplicativo Arquivos. A pasta Documentos aparece em uma segunda reconexão, mas não na terceira reconexão. Eu não vejo nenhum erro no dmesg.
Eu vejo isso sendo reconhecido via USB

Eu verifiquei este tópico em Como faço para acessar fotos da câmera iOS no Ubuntu 17.04? e corra
idevicepair validate
entendeu isso:
ERROR: Device returned unhandled error code "-3"
execute este
idevicepair unpair && idevicepair pair
e conseguiu validar com sucesso após inserir minha senha do iPhone, mas as pastas não voltariam a aparecer.
Depois de outra reconexão, vejo isso
idevicepair validate
No device found, is it plugged in?
Tentando acessá-lo via afc: // o esquema SerialNumber no aplicativo Files informa-me

Agora, a pasta Documentos é montada e mostrada, mas não são as Imagens .
Ao reconectar recebo essa caixa de diálogo de mensagem de erro (em Arquivos?)

Mas agora o afc: // começa a funcionar e finalmente posso ver pastas em Arquivos:
AirFair DCIM iTunesRestore PhotoData Purchases
Books Downloads LoFiCloudAssets Photos Radio
CloudAssets iTunes_Control MediaAnalysis PublicStaging Recordings
Portanto, pareço ter uma solução alternativa para acessar a pasta Fotos. Obviamente, gostaria que funcionasse sem as garras do sudo.
Isso funciona para mim, no Ubuntu 18.04: link
