Ho un computer veloce (ottimo processore, buon SSD) ma Software Center impiega ben 30 secondi per caricarsi. Questo non è un problema, penso che potrebbe esserci qualcosa di sbagliato. Synaptic impiega un secondo per caricare.
Corsi strace software-centera vedere se stava schiacciando il disco (è un SSD - non riesco a sentirlo) e sta bloccando e tentando di aprire un intero carico di file. Ecco un estratto:

Questa potrebbe essere un'aringa rossa. Più tardi si ferma a questo:
poll([{fd=3, events=POLLIN}], 1, 25000) = 1 ([{fd=3, revents=POLLIN}])
recvmsg(3, {msg_name(0)=NULL, msg_iov(1)=[{"l\2\1\1\v\0\0\0\3\0\0\0=\0\0\0\6\1s\0\7\0\0\0:1.3497\0"..., 2048}], msg_controllen=0, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 91
recvmsg(3, 0x7fff8c57cc00, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable)
sendmsg(3, {msg_name(0)=NULL, msg_iov(2)=[{"l\1\0\1\0\0\0\0\3\0\0\0{\0\0\0\1\1o\0\32\0\0\0/com/ubu"..., 144}, {"", 0}], msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 144
poll([{fd=3, events=POLLIN}], 1, 25000
E poi lo fa di nuovo ... Queste due pause rappresentano la maggior parte del tempo di caricamento.
E poi si capovolge davvero con migliaia di righe poll / read / temporaneamente non disponibili.
Quindi cosa sta succedendo qui? Perché Software Center sta scansionando quello che sembra essere un possibile pacchetto python che sta cercando StringIO? Bug?
Allora perché si blocca in quella che sembra una richiesta web a qualcosa.ubuntu.com (non riesco a vedere il messaggio completo)? Perché sta comunque parlando con ubuntu.com?
