I believe this occurred after I tried to change the name of my computer since it was a default and had a bunch of numbers after it.
After changing it, I started to experience weird things with my
sudo command, such as my password failing multiple times. A reboot ended up fixing that.
Now I am trying to run my
bitcoin-qt in the terminal.
It gives me this error:
bitcoin-qt: symbol lookup error: bitcoin-qt: undefined symbol: _ZN12QApplication10commitDataER15QSessionManager
I've tried to uninstall using --purge and reinstall. I've deleted the folder in
/usr/bin/bitcoin-qt and tried running it from that folder itself but still wouldn't work.
I'm not sure if there is a config file somewhere else that it uses but I've tried just about everything short of a complete OS reinstallation and nothing will work.
I did change my hostname in
/etc/hostname and even tried to change it back to what it originally was which was like "xxx-GL551JK" but my bitcoin core refuses to open.
I've tried running just the program itself too from the Search menu and that doesn't work either.
Edit 1: I just reinstalled a fresh copy of Ubuntu and the same error popped up. I literally had this thing running yesterday. I'm already pretty tired of Ubuntu. Almost nothing works out of box.
Edit 2: I just did a second reinstall while overwriting the entire SSD and installed it just the way I did the first time and it's all working again.
Edit 3: I've reinstalled this system I don't know how many times. Every time I reset my computer after downloading the Core, it gives me this lookup error. Literally have reinstalled 4 times and every time it occurs after restarting my computer. I've closed the application and even
sudo killall bitcoin-qt every time I tried to log off and then it inevitably gives me this same symbol lookup error. I've even tried 2 different versions of Ubuntu.
