I was trying to update my RPI. $sudo apt-get update , and this was my result:

Reading package lists... Done
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/
W: Problem unlinking the file /var/cache/apt/pkgcache.bin - RemoveCaches (13: Permission denied)
W: Problem unlinking the file /var/cache/apt/srcpkgcache.bin - RemoveCaches (13: Permission denied)

I later triedsudo apt-get update (no $ sign this time), and the result was:

Hit:1 http://archive.raspberrypi.org/debian buster InRelease
Hit:2 http://raspbian.raspberrypi.org/raspbian buster InRelease

W: Some index files failed to download. They have been ignored, or old ones used instead.

Then, I did sudo apt update and this is the result:

Is there anything I can do to fix this?

    "no $ sign this time" ... you should never type the $ sign!! it's just sudo apt-get update ... or alternatively, sudo apt update Jun 18 at 0:50

    that first error message suggests you ran the first command without sudo - that's exactly the error I get when doing so - because as sudo is not an environment variable, running $sudo apt-get update is identical to running apt-get update - in fact, you could do $someRandomStringOfLetters apt-get update and get the same problem - so, the first mystery is solved - please try running sudo apt-get update or sudo apt update again Jun 18 at 0:55

Unfortunately I don't have a high enough reputation to comment but make sure to include the asterisk (*) in the previous user's answer. The full command should be sudo rm /var/lib/apt/lists/* which will remove all of apt's cached package lists. You should then follow with this command: sudo apt update to see if your problem is resolved.

In addition to this, it looks like you have no disk space remaining on your SD card which may be part of your problem, can you provide the output of df -h to verify this?

Best of luck, Aidan.

  • Yes, it looks like your SD card is full, try the sudo rm /var/lib/apt/lists/* solution to see if that will free up sufficient space to run sudo apt update but I don't think you'll have enough space to actually upgrade or install any packages. Jun 18 at 16:43

try this

sudo rm /var/lib/apt/lists/*

in order to remove all the lists and

sudo apt-get update

to download the lists again.

have a nice day

  • When I do sudo rm /var/lib/apt/lists/ this is my result: rm: cannot remove '/var/lib/apt/lists/': Is a directory Jun 18 at 12:39
  • read the answer again ... sudo rm /var/lib/apt/lists/ isn't the same as sudo rm /var/lib/apt/lists/* Jun 19 at 1:50
