Might be a weird question or already answered but I created a standard wallet with segwit adresses (those starting with bc1) with Electrum 3.1.3.

Have Electrum 2.8.something on an old PC (think it's 2.8.1). Tried to restore the standard wallet with segwit addresses created with 3.1.3 from seed with Electrum 2.8.x and it won't recognize the seed. Checked multiple times, copy and pasted. No go. Is this because segwit adresses were only implemented with 3.0?

Yes, because the segwit addresses are not implemented yet when the 2.8.1 version released.

Also weird bug, when I type the seed of the wallet created with 3.1.3 to restore with 2.8.x at word 6 and half (!) of the seed suddenly the next button gets grey. When I click it it tells me I can restore a wallet with 2Fa now. When I click on this I get an error window with the possibility to send a bug report?

Don't use the old version because the old version of electrum doesn't recognize segwit addresses and lower than 3.0 version of electrum is always stuck on synchronizing.

Always make sure that you are using a latest version to be able to restore segwit addresses and there is bad news of using an old version. If you don't know yet you can read this Vulnerability discovered in Electrum 2.6 to 3.0.4: please upgrade

So you should use the latest version to keep your wallet safe.

It's because I run it on Ubuntu 16.04. LTS and upgrading of Electrum did not work. I get a python error message when I try to download the newest Electrum version, something wrong with pip in Ubuntu I believe.

Do you have the backup seeds or private keys?
I don't have much knowledge on using linux but check this thread and maybe it might help. https://bitcointalk.org/index.php?topic=2392090.0
