I have had this problem for about a week, i cant install , autoremove, or update without the problem showing up, since i tryed to update the kernel and it stays the same , i assume the problem comes from the kernel.

E: Sub-process /usr/bin/dpkg returned an error code (1)

Example of autoremove:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following packages will be REMOVED:
  linux-image-5.8.0-53-generic

The pertinent error message is /usr/sbin/grub-mkconfig: 34: /etc/default/grub: Syntax error: EOF in backquote.

Find the bad line with

grep -n '`' /etc/default/grub

fix that.

Output : noblelip@noblepc:~$ grep -n '`' /etc/default/grub 9:GRUB_DISTRIBUTOR="`lsb_release -i -s 2> /dev/null || echo Debian`" 23:# you can see them in real GRUB with the command `vbeinfo' Know any solution?

Read `man sudoedit` and `sudoedit /etc/default/grub`. Goto line 9, and erase the "`" 23:`" characters. Erase any backtick ("`\`") at end-of line. Save the file.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
