Sveiki. Is naujo perrasiau Ubuntu 18.04, ir bandant instaliuoti Wine, ar kai kurias kitas programas ismeta stai tokias problemas. Ieskojau atsakymo internete, bet galu gale ismesdavo tas pacias problemas.

Pradėkim nuo to, kad ne SS reikia įkelti, o žmoniškai nukopinti visą reikalą iš terminalo. Laikai, kai bičiuliai (su šampano butelio dugnais vietoj akinių) mielai siųsdavo vieni kitiems fax'us arba apsikeisdavo terminalo nuotraukomis paštu, baigėsi turbūt kokiais 1999m (senokai bliamba).

Ką turi /etc/apt/sources.list?

sudo cat /etc/apt/sources.list{,.d/*}

Taip pat, kokius apt paketus esi įsidiegęs?

sudo dpkg -l '*apt*' | awk '/^ii/'

sudo cat /etc/apt/sources.list{,.d/*}

pašalink mirrorus su old-releases
Taip pat pašalink visus ppa kurie tau duoda klaidas ir apskritai reikėtu vengti tų ppa nes jie dažnai būna neatnaujinami arba būna nepasiekiami - geriau pačiam tada įsidiegti tai ką siūlo automtiškai įdiegti ppa

As taip jau ir padariau, kazkaip pavyko susirasti visai atsitiktinai, nes norejau susitvarkyti steam ir pakeiciau kazkodel padarytus senus mirrorus i naujus. Bet vis tiek labai aciu. :)
