Hi, I am seeing the following error messages when running the command sudo apt install clang

similar happens with libclang-dev:

browsing the https://repo.pureos.net/pureos/pool/main/l/llvm-toolchain-7 URL, I can see the packages are there, but all of them have a ā€œ+deb10u2ā€ included in the name (libclang-common-7-dev_7.0.1-8+deb10u2_amd64.deb, which is different from the file name on the first URL libclang-common-7-dev_7.0.1-8_amd64.deb for example).

Is this something configured incorrectly on my system? If so, could anyone provide me some help on how to solve it?

PS: I already tried the solutions suggested by apt (ā€œmaybe run apt-get update or try with --fix-missing?ā€). In fact, when I try running apt install with --fix-missing, I get an additional error line which says: ā€œUnable to correct missing packages.ā€

PSS: This problem only happens with these 2 packages. I was able to successfully install several other packages without any issues

2

And you already did? :

sudo apt-get clean
sudo apt-get update
3

Just tried running sudo apt-get clean and then sudo apt-get update, but when running sudo apt install clang afterwards I still get the same error messages

4

:frowning: yea ok. I am on Byzantium and it works, I am no help to you.

5

Is the - between apt and get necessary? I donā€™t use the dash on Mint . The - causes me problems.

6

In my case it is, otherwise I get the error:

sudo: aptget: command not found

7

sudo apt get

9

itā€™s apt-get install clang

apt and apt-get are not the same tool

10

I understand. But it works on Mint without the - between the apt and the get. Different OS(distros?) use different syntax huh?

11

Im lazy so i sudo to root
And i stopped using apt-get because of something that Parrot told me.
( the distro not the bird )
I donā€™t remember what it was but I stopped using apt-get

Anyway - it works for me.
Wish i could be more helpful.

Thanks. Iā€™ll have to check with TDL my linux buddy , heā€™s been linuxing for years. Anything interesting iā€™ll report back later. Again thanks.

Iā€™m sorry for the late reply, but using sudo apt-get install clang after running sudo apt-get clean and sudo apt-get update also didnā€™t work

14

I see that in this case apt actually ā€œresolvedā€ to the correct URL (the one with the +deb10u2). Iā€™m wondering why itā€™s not doing the same in my case.

15

Youā€™re getting a bunch of 404 errors, that means it canā€™t locate the repo that has the packages youā€™re looking for (itā€™s probably down for some reason). You can wait it out or switch to a different mirror. I canā€™t off top of my head remember how to do the latter on a Debian OS, but it should be easy to find out.

16

The repo is actually not down. As I mentioned in my question, I can browse to the repo and even find the packages there, but for some reason my system is looking for the packages without the +deb10u2 into the name. If you look at @nonattributionā€™s post, youā€™ll see that in his case, his system is looking for the correct package name

17

Oh I see, I missed a few crucial details. Though I did notice you typed clang and (s)he typed libclang-dev.

18

Donā€™t think it pertains but the only way Mint 20.1 accepts my terminal commands is ; sudo apt get . Anything else doesnā€™t work. Sorry if Iā€™m off topic.

19

I donā€™t know if this is a good solution, but using the Debian mirror worked for me:

deb http://cdn-fastly.deb.debian.org/debian stable main

I found it on this url: https://deb.debian.org/

Could someone advise me on if it is a good practice to keep this mirror on my /etc/apt/sources.list?

20

A bad practice

i missed the notifications for your reply, sorry!
I knew i was too burnt out last week to be of much help - but -
Looking now i see that you are getting a different version
I have installed Version: 1:7.0-47
It looks like you are trying to install version Version: 1:7.0.1-8+deb10u2

try sudo apt install clang-7
instead of sudo apt install clang
( or apt-get if you prefer )

Also - you can usually download the package and install it with dpkg -i filename.deb
Edit ( but using d[kg like can screw things up at times - i.e. break packages temporarily etc )
