I found out the solution! Whether resume feature works or not depends on the server. In System->Administration->Software sources, choose Main Server (archive.ubuntu.com) and it will work. When I run an update or installation from ru.archive.ubuntu.com , resume does not work.
Can people at Canonical work together with mirror supporters to find out what prevents resume on some mirrors? -- timeouts using synaptic and update-manager https://bugs.launchpad.net/bugs/345943 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
