all files changed from read & write to read only without my permission

in flag

I upgraded to ubuntu 21.10 and it changed my files to read only. Now I can't create new folders or copy and paste files. States that destination is read only and cannot copy or paste.

Which files/directories/locations are read-only?

please [edit] your question to include what you upgraded from to 21.10 and how that upgrade was achieved.

If you are in your home, you can go to /home/ and do a `sudo chown -R yourname:yourgroupe yourdirectory` if you mean it is anywhere else edit your question

I think your filesystem may be mounted read only, possibly because of an error. Try reviewing the output of `mount` and `sudo dmesg`

@francoisP A `chown` would **never** be the right answer.

Your disk is probably in read-only mode due to file system errors.

  • boot to a Ubuntu Live DVD/USB in “Try Ubuntu” mode
  • open a terminal window by pressing Ctrl+Alt+T
  • type sudo fdisk -l
  • identify the /dev/sdXX device name for your "Linux Filesystem"
  • type sudo fsck -f /dev/sdXX, replacing sdXX with the number you found earlier
  • repeat the fsck command if there were errors
  • type reboot

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.
