[00:53] <neoromantique4> Hello, I've just installed fresh image of 21.10 and I cannot install build-essential :) 
[00:54] <neoromantique4> https://pastebin.ubuntu.com/p/drb9hMchcw/
[01:00] <Bashing-om> neoromantique4: ' sudo apt update ; sudo apt full-upgrade ' done prior ?
[01:00] <neoromantique4> Of course
[01:02] <tomreyn> can you post    apt policy && apt policy g++-11 gcc-11 libc6-dev
[01:03] <tomreyn> ...to a pastebin
[01:03] <neoromantique4> https://pastebin.ubuntu.com/p/S93Zf2gMbN/
[01:04] <neoromantique4> Is it useful to switch to a different mirror than default, or is it unlikely to be related?
[01:04] <neoromantique4> default being autodetected local one 
[01:08] <neoromantique4> Yes, that was the culprit 
[01:08] <neoromantique4> lt (Lithuania) mirror is defective or out of date, I switched it for GB mirror and instantly got 600mb of updates 
[01:09] <Bashing-om> \o/ neoromantique4 
[01:10] <tomreyn> https://launchpad.net/ubuntu/+mirror/ftp.litnet.lt-archive doesn't know about it being out of date
[01:11] <neoromantique4> perhaps it was a different bug, but point is that the only change I did was s/lt/gb/ in my sources, and that helped it
[01:11] <tomreyn> i'm wondering whether you had security.ubuntu.com in your apt sources.list, though
[01:11] <neoromantique4> it could be also some weird cache & changing main sources punched through it
[01:12] <tomreyn> actually this is pre-release, security is probably empty for impish. but maybe there is impish-updates and you're lacking this, or were
[01:13] <neoromantique4> tomreyn: deb http://security.ubuntu.com/ubuntu impish-security main restricted + universe + mugb.verse
[01:13] <neoromantique4> well, I literally just used latest ISO and installed it like 30 minutes ago
[01:14] <tomreyn> http://security.ubuntu.com/ubuntu/dists/impish/ not empty at all
[01:14] <tomreyn> it's not unusual for pre-release installers to not enable all the repositories
[01:15] <neoromantique4> should I disable security or enable? 
[01:15] <neoromantique4> It was enabled intially and I didn't touch it
[01:15] <tomreyn> should be enabled. also impish-updates
[01:16] <neoromantique4> https://pastebin.ubuntu.com/p/ps7bywjx55/
[01:18] <tomreyn> interesting, i never heard about "mugb.verse"
[01:19] <tomreyn> i assume that's supposed to be "multiverse"?
[01:19] <tomreyn> ah you ran sed s/li\./gb.\/
[01:20] <tomreyn> actually    sed -i 's/li./gb./'
[01:21] <tomreyn> regex laziness can have drastic results.
[01:28] <neoromantique4> ohhh, that's interesting, as I've ran lt./gb./ I assumed it would only get the literal dot
[01:28] <neoromantique4> oh well, it was just to verify a theory and it worked, so I'll just repair it by hand and call it a day :)
[01:29] <neoromantique4> RC is supposed to come out tomorrow, right? Can I just upgrade to it, or it should be clean install?
[01:32] <neoromantique4> also interesting, my firefox tabs keep crashing, hmm
