During Ubuntu startup (not remember exactly, but no newer than 16.04)

I got error

Minimal Bash-like line editing is supported. For the firs word, TAB list possible command completions. Anywhere eise tab list possible device or file completions

Tried to fix this by following this instruction in russian from help.ubuntu.ru.
Note: english version is available on help.ubuntu.com.

Disk /dev/loop0: 1.5 GiB, 1612648448 bytes, 3149704 sectors

The primary GPT table is corrupt, but the backup appears OK, so that will be used.

The sudo mount /dev/sda2 /mnt

gives

    Ask Ubuntu is an English Only site. Please translate from Russian/Cyrillic into English using a translation service before posting your question. – Thomas Ward Aug 06 '18 at 15:24
  • @RupertSmith I translated your post. Important message above is The primary GPT table is corrupt, but the backup appears OK, so that will be used.. Please add output of sudo blkid ; lsblk to the question. If GPT is corrupt, then block devices may not be created. And of course write in English. – N0rbert Aug 06 '18 at 15:28
  • @ThomasWard please reopen. It is not user-friendly (OP seems to be newbie). Even after I have translated his post. You gave him 15 minutes. It is too fast. – N0rbert Aug 06 '18 at 15:31
  • @N0rbert "Too fast" or not, post contents can still be edited after closure and then that puts them into the Reopen queue whether it was mod-closed or not. I was also live-monitoring this post for the update (translation, etc.) so the need to request for reopening (or critiquing how quickly this was closed for not being in English) is unnecessary. – Thomas Ward Aug 06 '18 at 15:35
  • @N0rbert

    sudo blkid ; lsblk

  • @RupertSmith I recommend to download Boot Repair Disk and follow its instructions to recover GRUB. – N0rbert Aug 06 '18 at 16:17

  • @N0rbert Boot repair just gave me to create Bootinfo (only one button in app). Report here http://paste.ubuntu.com/p/gsXZM5mQH7/ . I launched OS with Try Ubuntu from USB – Rupert Smith Aug 07 '18 at 05:30
